GPS100 Firmware Versions

2.3.0.1(2015-03-12)

- Added support for new World Magnetic Model WMM2015 to make magnetic variation calculation as accurate as possible

2.0.2(2010-02-11)

- Updated the magnetic variation function to use the new WMM2010 coefficients. This corrects a problem where magnetic variation is not available, which causes true heading readings to be unavailable or missing

2.0.1 (2009-03-23)

- Adds support for version 2 of the GPS hardware

-Updates GPS chipset firmware to a newer version

 1.6.14 (2009-03-04)

- Added support for the device to be labeled with a text string, making it easily identifiable in N2KView and DSM250

- Added ability to change the transmission rate of periodic messages

 1.6.13 (2008-08-07)

- Corrected occasional GPS unlocks

 1.6.10 (2008-04-22)

- Execute SiRF factory reset (clear BBSRAM and RTC) on every system reset

- Execute SiRF factory reset when SiRF bad date detected

 1.6.9 (2008-04-08)

      -    Corrected a problem when the GPS would sometimes report a date 19 years in the future

      -    Made Date/Time data available only after valid satellites are detected

 1.6.8  (2008-03-03)

      -     Corrected a  problem which would cause the GPS to stop transmitting certain messages under certain conditions.

 1.6.7 (2007-05-07)

 1.5 (2005-05-12)

- Added support to enable or disable periodically transmitted messages

 1.4 (2005-03-18)

- Ensured that all position/COG data were transmitted as “Data Not Available” when there is no position fix.

- Added WMM2005 magnetic variation estimation

- Updated NMEA 2000 protocol version to 1.111

- Added PGN 127258 to the list of transmitted PGN’s

 1.3 (2005-01-28)

- Initial Public Release
