The data is being collected with Trimble NetRS receivers L2C-enabled firmware. The sites are globally distributed: South Africa, Norway, Antarctica, Hawaii, and Alaska with international host organization cooperation; a locally accessible test site (UNAC) is located at the UNAVCO Facility in Boulder, Colorado. For this demonstration, JPL performs the data offloading/downloading and uses the Facility's teqc software for translation to the RINEX format. The L2C data from this demonstration is available from JPL and in compact RINEX format from CDDIS via anonymous ftp, with L2C data starting intermittently on day 2005:294 (21 Oct 2005).

Galileo/GIOVE

Galileo Satellite

current Galileo constellation status: ESA — Galileo Navigation

Special note for GIOVE users:
The reported PRN for the GIOVE satellites depends on the receiver manufacturer and also the receivers model. Known examples:

Javad Triumph: reports GIOVE-A as PRN 01 and GIOVE-B as PRN 02
Leica GRX1200+GNSS: reports GIOVE-A as PRN 01 and GIOVE-B as PRN 16 (presumably based on the information in the broadcast ephemerides)
NovAtel Europak15a: reports GIOVE-A as PRN 51 and GIOVE-B as PRN 52
Septentrio GeNeRx1: for firmware prior to 4.1, reported GIOVE-A as PRN 51 and GIOVE-B as PRN 52; for firmware 4.1 and higher (at least to 5.0), allowing for full signal capabilities of GIOVE-B, PRN 53 is used for full signal capabilities and PRN 52 continues to be used for the earlier subset of signal capabilities
Septentrio AsteRx2, AsteRx3: reports GIOVE-A as PRN 32 and GIOVE-B as PRN 31
Trimble NetR9: reports GIOVE-A as PRN 51 and GIOVE-B as PRN 52

The SVIDs of PRN 01 for GIOVE-A and PRN 16 for GIOVE-B are those defined in the GIOVE-ICD and are what is found in the transmitted BCEs. The GIOVE-ICD also states that these PRNs will be re-used for the future IOV and FOC satellites.
