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
BDS = BEIDOU
