SP-12 GPS
14 CFR §91.227c, AC 20-165B, Appendix B
compliant GPS receiver
(TSO-C199 TABS GPS qualified for SIL 3 and SDA 2)
The SP-12 is based on the Aspen Avionics NexNav Micro-i GPS module used by several avionics manufacturers. It provides a simple and low cost solution to the FAA 2020 mandate.
It provides the standard Micro-i NMEA output on RS232 but adds user selectable baudrates (the default is the standard 115200 baud used by the Micro-i module).
In addition it packs the NMEA data from the Micro-i onto the CAN bus for direct use by an MGL EFIS or compatible transponder without the need for further wiring. (Only the Trig transponder via the MGL Avionics interface is compatible at this point). The MGL Avionics T-16 transponder is of course also supported (this device is currently in development).
If you are using an older version of the MGL interface to the Trig transponder it requires a firmware update to support the SP-12. This firmware can be downloaded on this page with update instructions.
