BACKGROUND Autonomous regional satellite based navigation systems have enabled several countries to cover their territorial footprint and the footprint of their surrounding areas. A regional satellite based navigation system such as a global navigation satellite system (GNSS) caters to the needs of specific users, for example, military personnel for military applications, and civilian users for civilian applications. For example, India is planning to deploy an autonomous regional satellite navigation system, namely, the Indian regional navigational satellite system (IRNSS), for surveying, telecommunication, transportation, identifying disaster locations, public safety, etc. The purpose of this navigation system is to cater to the needs of both standard positioning service (SPS) users and also to the needs of restricted service (RES) users. The SPS and the RES modes of service are dual services supported by any GNSS catering to civilian and military requirements exclusively. A military signal is generally acquired in two modes, namely, direct and indirect. The indirect mode is typically known as SPS assisted. There is a need for generating navigation data structures that address the needs of the SPS and RES modes of service. Specifically, for the RES signal, there is a need for the navigation data structure to account for the direct mode of acquisition or the SPS assisted mode. In the SPS assisted mode, with assistance from time of week (TOW) data, the jump on to the RES signal is established. The IRNSS will deploy a satellite constellation comprising seven satellites, three of which will be in geostationary orbits and four in geosynchronous orbits. The signals will be transmitted by the satellites in two frequency bands, namely, L5 frequency band (1176.45 megahertz (MHz)) and SI frequency band (2492.08 MHz). The SPS signal will be modulated by a 1 MHz binary phase shift keying (BPSK) signal, whereas the PS signal will use a binary offset carrier, BOC (5, 2). A number of issues need to be addressed while designing a satellite navigation system, for example, sensitivity improvements, jamming margins, robustness towards spoofing, multipath related improvements, time to first fix (TTFF), etc., for ensuring the efficiency and robustness of the satellite navigation system. Time to first fix (TTFF) is an important parameter that needs to be optimized in most satellite navigation receivers. TTFF is a measure of the time taken by a satellite navigation receiver to acquire satellite signals and navigation data, and output a first position solution, referred to as a "fix", from power-on. The TTFF parameter directly influences the efficiency of position tracking by the satellite navigation receiver. The TTFF parameter has been examined at length and several approaches have been proposed to reduce this parameter. However, most of the approaches have concentrated on augmenting the satellite navigation receiver with data aid to the satellite navigation receiver. For an optimal TTFF performance, it is necessary that the time taken for computing navigation measurements and collecting subsequent navigation data is minimal. Typically, methods for reducing TTFF have focused on reducing the time required to acquire and lock the navigation signal, assisting the satellite navigation receiver with navigation data on a separate satellite link, etc. However, these methods are generally expensive in terms of deployment costs, complexity of the satellite navigation receiver, etc. [0001] A typical global navigation satellite system (GNSS) signal may be characterized by the following equation: s(t) = c
