NexNav Max GPS CCAs include part numbers 31000S and 33000S. The NexNav MAX GPS SBAS is a satellite receiver that utilizes the signals coming from Global Positioning System (GPS) satellite constellation and satellite-based augmentation systems (SBAS).  Wide Area Augmentation System (WAAS) is one example of SBAS.  It also supports EGNOS, MSAS and GAGAN to the extent they are compatible with WAAS.

These are GPS receiver CCAs designed and conformed to meet the requirements of US FAA TSO C145c and intended to be embedded in various avionics products produced by other manufacturers.  Their primary function is to provide aircraft position, aircraft velocity and precise time and provide the output to the host system, such as a transponder.

Part numbers 31000S and 33000S share common hardware, but have different software controlled functionality. Both have an SMA-type antenna connector and a 40-pin dual row connector for all other input/output. They both support the RS-232 based NexNav binary interface protocols.

Part number 31000S conforms to the functional requirements of RTCA DO-229D, Change 1 for WAAS Class Beta 1 articles.  Part number 33000S conforms to the functional requirements of RTCA DO-229D, Change 1 for Class Beta 1, 2, 3 articles.  US FAA TSO C204 approval is pending for both.  All NexNav MAX receivers meet the requirements of US FAA Advisory Circular 20-165B for ADS-B GPS source.

The NexNav Micro-i GPS SBAS is a satellite receiver that utilizes the signals coming from Global Positioning System (GPS) satellite constellation and satellite-based augmentation system (SBAS).  Wide Area Augmentation System (WAAS) is one example of SBAS. It also supports EGNOS, MSAS and GAGAN to the extent that they are compatible with WAAS.

NexNav Micro-i GPS products, modules and GPS sensor units, have been designed to meet the requirements of both TSO C199, Appendix 1, Section A1.2.6 for TABS and the position source performance requirements of 14 CFR §91.227(c) for ADS-B OUT. Accordingly, the currently targeted applications for the NexNav Micro-i GPS products include aircraft exempted from carrying a transponder or ADS-B equipment (such as gliders, balloons and aircraft without electrical systems) optionally equipped with TABS and experimental aircraft requiring a 14 CFR §91.227 compliant ADS-B OUT position source. Depending on how the regulatory and policy situation evolves, potential future applications for NexNav Micro-i GPS products could include use as a 14 CFR §91.227 compliant ADS-B OUT position source on UAS platforms and on Part 23, Class I & II TC’ed aircraft.

The primary function of Micro-i is to compute the position, velocity of an aircraft and the precise time (PVT) and provide the output to the host system, such as a transponder. It also computes the integrity of the PVT from the SBAS signal, if available. Micro-i detects the failed satellites (FD) using receiver autonomous integrity monitoring (RAIM) algorithm, whenever there are enough number of satellites to support the FD.

The NexNav Micro-i GPS SBAS OEM module receiver includes part numbers 14000-1 and 14000-4.  The 14000-1 part number indicates a refresh rate of 1 Hz and the 14000-4 part number indicates a refresh rate of  4 Hz.  Except for the refresh rate differences the two part numbers share the same form, fit and function.
