TECHNICAL FIELD
[001] The present invention is related to satellite imagery, and more specifically to a system and method for streaming high-resolution videos from low-Earth orbit.
BACKGROUND OF INVENTION
[002] Since the mid-twentieth century, Earth observation (EO) has always been about capturing and analysing satellite images of the landmass, water bodies, elevation, and other physical, chemical, and geographical aspects of the earth. The first photograph of the Earth was taken in 1946 by the motion picture camera aboard the White Sands rocket. Many satellites have been launched into orbit since then to capture high-resolution images of various parts of the globe. In 2014, NASA set a new standard by installing four commercial high-definition video cameras on the exterior of the European Space Agency's Columbus laboratory module. These four cameras captured high-definition videos from various angles on a repeating cycle, and the onboard systems streamed them to Earth.
[003] In another case, a UK-based company successfully prototyped a space television concept by installing a 4K Ultra high-definition camera in low earth orbit to test their live video streaming capabilities. The orbital setup of the company, which is still in the testing phase of its pan-tilt-zoom (PTZ) capabilities.
[004] In a conventional mechanism, wherein an electro-optical sensor based on multi-megapixel two-dimensional charge-coupled device (CCD) arrays mounted on a geostationary platform is used for collecting and distributing real-time high-resolution images of the Earth from Geostationary Earth orbit (GEO). Global coverage is provided by at least four three-axis stabilised satellites in GEO, excluding the poles. The image data is collected at approximately one frame per second and broadcast over high-capacity communication links (roughly 15 MHz bandwidth), providing real-time global coverage of the Earth at sub-kilometre resolutions directly to end users. This data can be distributed globally from each satellite through a system of space and ground telecommunications links. Each satellite carries at least two electro-optical imaging systems that operate at visible wavelengths to provide uninterrupted views of the Earth's entire disc as well as coverage of most or selected portions of the Earth's surface at sub-kilometre spatial resolutions.
[005] In yet another conventional mechanism, a real-time Satellite Imaging System is disclosed. More specifically, an imaging sensor on a geostationary satellite with one or more co-collimated telescopes, where the telescopes illuminate focal planes sparsely populated with focal plane arrays. The focal plane arrays record the entire observable Earth hemisphere at once, at least once every ten seconds, if not more frequently.
[006] In yet another conventional mechanism, a compact high-definition hyperspectral imaging system (HDHIS) for light aircraft remote sensing performs simultaneous push broom hyperspectral imaging and high-resolution photographic imaging. The HDHIS consists of a sensor head with a hyperspectral scanner and a Charge-coupled device (CCD) digital camera. An airborne computer interfaces with the sensor head to provide data acquisition, including hyperspectral quick view images and control functions. In another embodiment, the HDHIS is combined with a computerised airborne multi-camera imaging system (CAMIS), which consists of four progressive scan (CCD) cameras attached to a set of interchangeable interference filters, to provide a triple spectral imaging system that can be operated by one person on a light aircraft.
[007] In yet another conventional mechanism, a system is configured for processing large amounts of Earth observation image data. The system consists of a computer with a visual display and a user interface, a plurality of servers, an image database for storing the Earth observation imaging data as a plurality of separate image data files, and a network for connecting the computer, number of servers, and image database. The plurality of servers can process the separate data files in a distributed manner, at least one of the servers can process the separate data files in a multiprocessing environment, and at least one of the servers can collate the processed separate data files into a single imaging result.
[008] In yet another conventional mechanism, a system, method, and apparatus for obtaining and distributing live and real-time video imagery of the Earth, Earth's local space environment, the Moon, celestial bodies, and any events or objects visible to a low Earth Orbiting space-based video imaging system that is interactively controlled by an operator using an internet-connected computer. A low-Earth orbit (LEO) spacecraft serves as the platform for the suite of multi-axis-controlled video image sensors. The spacecraft's communication system provides the high data rate downlink (and lower rate uplink) via one or more multiplexed S- or X-band transceivers. The transceiver (s) broadcast the video stream to one or more remote transceiving stations located around the world. The transceiving stations are directly connected to the internet and provide live real-time streaming of the downlinked imagery data. The internet-connected remote ground stations also provide a real-time interactive control environment (less than 3 seconds for an interactive loop) in which any authorised operator can actively control one or more of the onboard video image sensors.
[009] In yet another conventional mechanism, a multi-megapixel, two-dimensional, charge-coupled device (CCD) array mounted on a geosynchronous orbit platform is used to collect and distribute real-time, high-resolution images of the earth from a GEO. Except for the poles, at least four three-axis stabilised satellites in geosynchronous earth orbit (GEO) provide global coverage. Image data collected at approximately one frame per second is broadcast over a high-capacity communication link (approximately 15 MHz bandwidth) to end users, providing real-time global coverage of the earth with a resolution of less than one kilometre. This data can be generally distributed from each satellite by a system of space and terrestrial communication links. Each satellite has many visible wavelengths operating at a spatial resolution of less than one kilometre and providing an unobstructed view of the Earth's full disk and coverage of most or a selected portion of the Earth's surface. This conventional mechanism uses two electro-optical imaging systems.
[0010] Another conventional mechanism has been disclosed, in which a system autonomously maps and tracks ground targets at a point of interest. The system consists of at least one user control centre in operational communication with one or more data relay satellites in Geostationary Equatorial Orbit (GEO), the data relay satellites in operational communication with one or more UAVs and/or SAR satellites with various imaging sensors on-board to obtain various types of imagery data from ground targets. The data relay satellites are designed to maintain constant communication with the user control centre, as well as with the UAVs and SAR satellites, to provide continuous feedback and control. Furthermore, the system processes all raw data collected by UAVs and SAR satellites to generate 2D and 3D Digital Elevation Models (DEMs) and high-resolution images, which are displayed on the user control centre and/or selected mobile handheld devices.
[0011] In yet another conventional mechanism, a line-scanning satellite constellation is launched that can image an entire planet such as the Earth at high temporal cadence (less than a week) at high spatial resolution (less than 10 m). This mechanism employs a simple control and operation to capture images of an entire planet in an efficient and distributed manner. This mechanism aids in the distributed onboard storage and computing capabilities of such a constellation to optimise data collection, system latency, and data downlinking.
[0012] However, conventional mechanisms have a number of flaws, disadvantages, and issues. In a nutshell, streaming high-definition videos from space is a technically challenging task that requires a high level of expertise on multiple fronts. As a result, a system and method for streaming sub-meter resolution videos from low earth orbit are required to overcome the shortcomings, disadvantages, and problems in the conventional mechanism.
[0013] The aforementioned shortcomings, disadvantages, and problems are addressed herein, and will be understood by reading and studying the following specification.

[0029] The optical payload unit 202 of the at least one satellite 200 is configured to capture a high frequency/resolution image sequence or video of a user defined area-of-interest or target. The at least one satellite 200 is orbiting around the earth in low earth orbit. In an embodiment, the at least one satellite 200 is a cluster of nano satellite (s) 200 orbiting around the earth in the low earth orbit. In an embodiment, the user-defined area-of-interest can include, but is not limited to, flooded rivers inundating residential areas as a result of heavy rainfall, cyclones in the coastal region and related damages, military requirements specifically for monitoring an international land or sea border, monitoring live traffic and/or tracking smugglers/chasing thieves, monitoring forest fires, or analyzing earthquakes over a specific area, and international fishing conflicts. Further, the optical payload unit 202 is configured to determine and correct a distortion in the captured high frequency image sequence. For example, motion corrections from both target movement on the ground and platform movement in orbit, platform attitude disturbance correction, and atmospheric noise correction. In an embodiment, a noise present in the image sequence is analyzed and reduced using an image processing technique. In an embodiment, the image processing technique includes, but is not limited to, differential information collection, motion vector generation, and entropy encoding using machine learning and artificial intelligence (AI) techniques for low-bit-rate transmission. Further, the video processing unit 204 is configured to format dynamic features of the high frequency image sequence into a sequence of reduced image frames by displaying only an inter-frame change or movement without repeating movement less frames using a differential technique. In an embodiment, the dynamic features include generating a motion vector for the target's high frequency image sequence. In an embodiment, machine learning and AI tools are used for image/video processing. In another embodiment, the differential technique aids in the separation of moving data from static data within each frame of the image/video sequence. Further, the video processing unit 204 is configured to compress the sequence of reduced image frames for encryption. Further, the encryption unit 206 is configured to encrypt the compressed sequence of reduced image frames and meta data into the dynamic data layer and the quasi-static data layer. Further, the modulating unit 208 is configured to modulate the encrypted sequence of reduced image frames and meta data for transmission. Further, the transmitter circuit unit 210 is configured to transmit the modulated sequence of reduced image frames and meta data to the ground station 300 through the X band.
[0030] According to the embodiments, the ground station processing server unit 302 is configured to receive the modulated sequence of reduced image frames and meta data from the satellite 200 for streaming high-resolution videos. Further, the de-modulating unit 306 is configured to de-modulate the received modulated sequence of reduced image frames and meta data. Further, the decrypting unit 304 is configured to decrypt the demodulated sequence of reduced image frames and meta data and transmit the decrypted sequence of reduced image frames and the meta data to a centralized server unit 308. Finally, the centralized server unit 308 is configured to transmit the de-modulated sequence of reduced image frames and meta data to a user electronic device for live video streaming/streaming high resolution videos. The user electronic device can be at least one of but not limited to a mobile phone, a personal digital assistant (PDA), a tablet, a computer, a smart watch, or any other electronic device capable of receiving and playing multimedia information.
[0031] According to the embodiments when a client or user signs into a secure portal on the electronic device. The user can view maps and request live streaming of a specific location by entering the location's latitude and longitude or by entering the location name. When the location information (latitude and longitude or location name) is received, the portal displays that specific location. If the given place already has pre-recorded videos, the secure portal can play the pre-recorded videos to the user. However, if the specified location does not have any pre-recorded videos in the secure portal, the user can submit a task request to obtain live video streaming of that specific location.
[0032] ] In an embodiment, when the secure portal receives a task request, the nearest feasible satellite 200 is tasked with streaming live video of the specific location. The follow-on units (one or more satellites) that are assigned to pass over that specific location are also tasked with the same request at that particular time.
[0033] According to the embodiments, the satellite 200 and the ground station 300 comprises a memory/storage (not shown). In an embodiment, the memory of the satellite 200 is configured to store the captured high frequency image sequence of the user defined area-of-interest. In another embodiment, the memory of the ground station 300 is configured to store the modulated sequence of reduced image frames and meta data of the area-of-interest received from the satellite 200 to broadcast live streaming. The memory may include one or more computer-readable storage media. The memory may include non-volatile storage elements. Examples of such non-volatile storage elements may include magnetic hard discs, optical discs, floppy discs, flash memories, or forms of electrically programmable memories (EPROM) or electrically erasable and programmable (EEPROM) memories. In addition, the memory may, in some examples, be considered a non-transitory storage medium. The term “non-transitory” may indicate that the storage medium is not embodied in a carrier wave or a propagated signal. However, the term “non-transitory” should not be interpreted to mean that the memory is non-movable. In some examples, the memory can be configured to store larger amounts of information than the memory. In certain examples, a non-transitory storage medium may store data that can, over time, change (e.g., in Random Access Memory (RAM) or cache).
[0034] FIG. 1 shows exemplary units of the system 100, but it is to be understood that other embodiments are not limited thereon. In other embodiments, the system 100 may include less or more number of units. Further, the labels or names of the units are used only for illustrative purposes and does not limit the scope of the invention. One or more units can be combined together to perform same or substantially similar function in the system 100.
[0035] FIG. 2 illustrates a space LEO constellation for streaming high resolution videos from low-earth orbit, according to an embodiment as disclosed herein. The satellite 200 cluster is depicted in different orbital inclinations in FIG. 2, with two of the inclinations in a sun synchronous orbit (SSO) and a central one in a polar orbit. The majority of the cluster's satellites (s) 200 are strategically situated in the SSO to capture the entire Earth at a high temporal cadence.
[0036] FIG. 3 illustrates the operational mode of a satellite 200 to capture the high frequency image sequence of the user defined area-of-interest/target, according to an embodiment as disclosed herein. In an embodiment, if the satellite 200 is configured to capture a particular target, the satellite 200 is set to an imaging/capturing mode to receive the latitude and longitude of the targets. Further, the nearest passing satellite 200 is designed to capture the target with high resolution and high frequency frame rate based on the latitude and longitude of the received target.
[0037] In another embodiment, if the target is not captured, the next available satellite is automatically tasked with obtaining the requisite sequence of frames during the next available immediate pass.
[0038] In yet another embodiment, if the target is to be consistently captured over a period of time (for example, a week), a specific number of satellite (s) 200 are dedicated to the task for that time period. The target's latitude and longitude can be locked, and the satellite(s) 200 are tasked with capturing the target on every day pass. Finally, once the satellite(s) 200 has successfully captured the assigned target, the satellite(s) 200 is free to perform other tasks.
[0039] In yet another embodiment, if the satellite (s) 200 is not assigned any task, the satellite (s) 200 can continue to capture single frames of all the areas they pass through on the sun-lit side of the Earth.
[0040] FIG. 4 illustrates the system 100 wherein the captured high frequency image sequence of the user defined area-of-interest/target is transmitted back to the earth, according to an embodiment as disclosed herein. In an embodiment, the captured high frequency image sequence of the user defined area-of-interest/target is transmitted back to the ground station 300 available at that point in time during every pass, which lasts about ten minutes when facing the ground station 300. The high frequency image sequence of the user defined area-of-interest/target is consistently captured and transmitted to the ground station (s) 300 for processing and storing, so that prospective clients can use them as and when required.
[0041] FIG. 5 illustrates the system 100 for capturing the high frequency image sequence of the user defined area-of-interest/target from the satellite and broadcasting a live streaming to an end user, according to an embodiment as disclosed herein.
[0042] According to the embodiments, the ground station(s) 300 is networked and connected to the centralized server unit/centralized cloud server 308. The centralized cloud server 308 can be of our own or installed by a third party. The centralized cloud server 308 synchronizes, decompresses, and decrypts the captured high frequency image sequence of the user-defined area-of-interest/target, received by the ground station (s) (300). The centralized cloud server 308 further transmits the data (i.e., the captured high frequency image sequence) to an artificial intelligence (AI) portal/secured portal that employs machine learning (ML) techniques. These machine learning techniques can enable object identification capabilities, which can assist the end users with a required data analysis.
