Status

Q: Is there a way to monitor the stream status of each site?
A: Yes. To keep track of the active status in real-time, the best method is to enable station statistics and tail -f each station. Alternatively, you can tail -f the main rtes log file, but it can be a lot of information if debug logging is enabled. To enable saving station statistics, the RTES input file must not have the disable_station_statistics option enabled. To simply check on the status of all stations simultaneously, use the request server status command (see http://www.gps-solutions.com/rtes/ - req_server_status_input for documentation of this command)


Q: Are there any state of health parameters saved that could be used to gauge transmission quality and robustness?
A: Yes. Use the station statistics files. Each file contains the following information:
# 5000 ms
# 19.6488000 -101.2278000 0.0000001
# sv_mp off
# quarter-cycle phase adjustment flag: disabled (adjusted by receiver)

The first column is the epoch time (UNIX time). The second column is the milliseconds of the epoch. The third column is MP1. The fourth column is MP2. The fifth column is the percentage of epochs received over the past hour. The sixth column is the percentage of epochs over the last hour that were received with OK latency. The default maximum latency is 5 seconds (you can change this value in the RTES input file). The seventh column is the number of epochs used to calculate these statistics. The eigth column is the number of satellites in this epoch. The ninth column is the number of satellites used in the MP1 calculation (usually the same number if all satellites observer L1 and L2). The tenth column is the latency in milliseconds. The 11th column is a simple flag of whether data is present for this epoch. Finally, there's a list of satellites observed for this epoch.


Station

Q: How do we add additional stations on rtes?
A: Use the start station command. See http://www.gps-solutions.com/rtes/ - start_station_input for details.


Q: How can we rebroadcast the binex stream for selected stations? Can we select the ip port for the rebroadcast on each site ?
A: You can configure RTES to create a NTRIP caster. You could use this to relay raw data. This is documented on the RTES documentation webpage. RTES currently cannot relay raw data on a simple TCP port, only with the NTRIP caster.


Archive of Data and Files

Q: Where to select the periodicity or duration of data files?
A: You can set the time window for each observation file by changing the option in the start station XML file. Please see http://www.gps-solutions.com/rtes/#start_station_input for details.
