Standards and Technical Details
Networking solutions:
Existing subnets are the Northeast Montana (NEMT), Northcentral Montana (NCMT), Northwest Montana (NWMT), Southwest Montana (SWMT), and Southcentral Montana (SCMT).
Network mountpoints (for example) for the NE subnet of MT (Fort Peck area) are:
Mountpoint | Data format | Constellation |
---|---|---|
NEMTVRSCMR | VRS mode CMR+ | GPS+GLN |
NEMTVRSRTCM3 | VRS mode RTCM3.1 | GPS+GLN |
NEMTVRSCMRx | CMRx | GPS+GLN+GAL+BDS |
NEMTVRS_MSM | RTCM3.4-MSM | GPS+GLN+GAL+BDS |
Multi-Station Solution (another format for single station solution):
Mountpoints under the prefix of MTSS_.
When a subscriber selects a MTSS_ solution, the MTSRN will select the closest station to the receiver.
Mountpoint | Data format | Constellation |
---|---|---|
MTSS_CMR_PLUS | CMR+ | GPS+GLN |
MTSS_RTCM | RTCM3.1 | GPS+GLN |
MTSS_CMRX | CMRx | GPS+GLN+GAL+BDS |
MTSS_RTCM_MSM | RTCM3.4-MSM | GPS+GLN+GAL+BDS |
Single station solution (shown for a station FTPP):
Mountpoint | Data format | Constellation |
---|---|---|
FTPP | CMR+ | GPS+GLN |
FTPP_3 | RTCM3.1 | GPS+GLN |
FTPPCMRx | CMRx | GPS+GLN+GAL+BDS |
FTPP_MSM | RTCM3.4-MSM | GPS+GLN+GAL+BDS |
RTCM and RTCM_MSM suffixes indicate internationally accepted standard formats compatible with any vendor’s data collector.
CMRx & CMR_PLUS suffixes indicate Trimble proprietary formats compatible for Trimble devices.
MSM and CMRx suffixes indicate multi-constellation solution.
Constellations:
GPS
GLN = GLONASS
GAL = GALILEO
