Daily RINEX products are stored online permanently. Hourly products are stored for several months. High-rate data products are stored online for at least 6 months. Older high-rate files are available by request, contact firstname.lastname@example.org.
Geoscience Australia collects 1Hz RTCM3 real-time streams from the ARGN, SPRGN and AuScope networks across a variety of communication methods. Usually, most sites will have latencies below 2 secs however because of the communication methods used at some sites, the latency can be larger than 2 seconds and potentially unusable as a base station stream for RTK purposes. Geoscience Australia provides access to real-time streams on a best effort basis and is unable to guarantee completeness or low latency on our real-time data streams.
Real-time stream access is freely available to the ARGN and SPRGN by subscription (please note no differential corrections are provided). For further information on accessing these data streams refer to GA_NTRIPCaster_Info.txt or contact email@example.com.
Metadata and station logs
Metadata and site information is maintained as an International GNSS Service (IGS) station logs. These files are in ASCII format and show the current and historical information about the station and its equipment.
The station log filename is composed of the 4-character marker name, followed by the 4-digit year, 2-digit month and 2-digit day e.g. alic_20111225.log is the site log for the CORS at Alice Springs, prepared on 25 December 2011.
