[IGSSTATION-8229] GRAZ: changed message types in realtime streams

[Titz Helmut]

Author: Helmut Titz, BEV, Austria

Dear colleagues,

the RTCM 3.2 message types of the realtime stream of the Austrian IGS station GRAZ provided via the mountpoint /GRAZ00AUT0 have been changed.
Due to a request of the Galileo Reference Centre (GRC) the ephemeris messages have been enabled.
The data messages have been switched from MSM5 to MSM7 to be fully compatible with the EPN station guidelines.

The following messages are contained in the /GRAZ00AUT0 stream from now on:

1006 (60 sec.)	Stationary Antenna Reference Point, with Height Information
1008 (60 sec.)	Antenna Descriptor & Serial Number
1033 (60 sec.)	Receiver and Antenna Descriptors

1019 (60 sec.)	GPS Satellite Ephemeris Data
1020 (60 sec.)	GLONASS Satellite Ephemeris Data
1042 (60 sec.)	BDS Satellite Ephemeris Data
1045 (60 sec.)	Galileo F/NAV Satellite Ephemeris Data
1046 (60 sec.)	Galileo I/NAV Satellite Ephemeris Data

1230 (60 sec.)	GLONASS L1 and L2 Code-Phase Biases

1077 (1 sec.)	Full GPS Pseudoranges, PhaseRanges, PhaseRangeRate and CNR (high resolution)
1087 (1 sec.)	Full GLONASS Pseudoranges, PhaseRanges, PhaseRangeRate and CNR (high resolution)
1097 (1 sec.)	Full Galileo Pseudoranges, PhaseRanges, PhaseRangeRate and CNR (high resolution)
1127 (1 sec.)	Full BeiDou Pseudoranges, PhaseRanges, PhaseRangeRate and CNR (high resolution)

The coordinates provided in message 1006 are national coordinates in the ETRS89 Austria 2002.56 datum.

At the moment we do not support BDS-III. We need to run an old firmware version on the Septentrio PolaRX5 receiver to be compatible with the currently used realtime software used in the Austrian Positioning Service APOS.

Best regards
Helmut
