Changelog:
Signal tracking improvements.
- The signal phase lock sensitivity in GPS mode has been improved when signal strength is below 30 dBHz. Tracking reliability is therefore generally improved in difficult situations such as strong temperature fluctuation, unstable clocks or extremely high receiver mobility.
Satellite system referencetime.
- When navigating using GLONASS the receiver converts GLONASS time to GPS time for output in some UBX messages. For the NMEA protocol this conversion is not needed, as the messages contain only UTC time, which can be easily derived from GLONASS time.
- NMEA talker identifiers. When operating in GLONASS mode the receiver uses the talker identifier GL, by default, instead of the GP identifier usually used in GPS mode. This can be overridden using the UBX-CFG-NMEA message.
One single external Flash image.
- Ubx 7 receivers with ROM 1.0 support on-chip Low Level Configuration, hence only just one Flash image is released. For detailed information refer to the UBX-G7020 Hardware Integration Manual.
Power Save Mode Performance
- Improvement of the Power Save Mode (PSM) has been implemented in order to reach even lower power consumption while maintaining excellent positioning performance. u-blox 7 features various configurations for Power Save Mode. For a full description of this new enhanced feature, refer to the u-blox 7 Receiver Description including Protocol Specification (GPS/GNSS) and the UBX-G7020 Hardware Integration Manual. Jamming immunity when in PSM cyclic operation has been further improved and cross correlation mitigation algorithms were added to cyclic operation.
