What's new in Superstar 2 FW 1.311 (release)---> June 2, 2006

FW 1.311 Release : Major Changes since FW 1.310
-----------------------------------------------
- a memory error fix in Msg#33
- the Msg#23 rate making slow data rates (< 1Hz) come out on times that are evenly divisible by the period of the message

FW 1.310 Release : Major Changes since FW 1.302
-----------------------------------------------
- Changed algorithm used to determine the time to apply the leap second change. Also removed duplicated function for determining leap second correction to apply.
- If a message type 0 is received from a WAAS satellite, then the channel tracking the satellite is reset, and another one will be tracked.
- 1PPS is not longer output in Navigation mode Initialized when 1PPS output control is set to only when receiver has position.
- The 1PPS width value is locked at 1ms now since the SSII hardware only outputs at 1ms.
- Reduction in satellite search times.
- Allow Msg 23 periods of 0.1s, 0.2s, 0.5s, 1s, 2s, 5s-240s, 10min, 30min, 60min.


FW 1.302 Release : Major Changes since FW 1.300
-----------------------------------------------
- SSII doesn't track satellites when saved position is very far from current position
- SSII sometimes is not tracking new satellites (smart-antenna)
- When requesting message 23 through message 105, message 23 comes out empty


FW 1.300 Release : Major Changes since FW 1.201
-----------------------------------------------
- Fixed a Viterbi decoding problem that was causing missed SBAS subframes
- Track SV Request command bug fixed
- Added option for models with 12 GPS channels and no SBAS
- Positioning improvements
- 2D positioning mode option added
- Default message list problem fixed
- NVM Clear command modified to restart receiver after erase is complete
- Missed accumulation date read problem fixed (was causing 5 second loss of lock)


FW 1.201 Release : Major Changes since FW 1.200
-----------------------------------------------
- Fix for the ephemeris logging problem



FW 1.200 Release : Major Changes since FW 1.102
-----------------------------------------------
- GPS tracking improvements (reduced number of loss of locks, reduced cross-correlation occurences)
- WAAS tracking improvements (better search logic)
- Turn SBAS positioning OFF by default
- Positioning improvements (Less position jumps, DGPS improved, initialized mode / dead-reckoning logic improved, IODE mismatch fix)
- Fix for GGA logs with invalid solution, Changed 1PPS hold off default value for timing models
- Fixed the NMEA logging rate problem for 1Hz logs saved with 999 option 
- Fix for RMC log at 5Hz 
- Fix for 999 option in NMEA PMCAG,005 command 
- Fix for NMEA Nav Status message logging rate 
- Cycle slip detection improvements
- Free up channels that cross-correlate
- Improved waypoint messages
- Improved WAAS message
- Improved base model operation including Self survey (Base Model config block 205 Only)


FW 1.102 Release : Major Changes since FW 1.101
-----------------------------------------------
- Reworked BIT to handle new flash types, and fixed the NMEA message list storage problem


FW 1.101 Release : Major Changes since FW 1.100
-----------------------------------------------
- Fixed problem with mask angle stored in NVM that could cause the receiver to reset at start-up



FW 1.100 was the first NovAtel Superstar 2 FW release
