 Multipath Type
: You must specify this setting in order to filter out interference in the satellite signals caused by
nearby objects.
 Dynamics
: This setting is applied to all Thales equipment types with the exception of the Z-Max. Here you may
specify the dynamics setting. Static is selected only when the Rover receiver is stationary. The default is Walking.
When set to Static, the HRMS and VRMS values (measurements of accuracy) will fall to very low numbers (high
accuracy), but lock will not hold unless the antenna is motionless. Static is recommended when the antenna and
pole are secured by a tripod or bipod.
 Ambiguity Fixing Parameter
: This controls the confidence level of fixed positions. The default is 99.0. At a lower
confidence interval the system solves much faster. If the system incorrectly solves the position, then the position
error will be much greater than the reported RMS value.
 Fast CPD
: This option specifies whether or not the program will allow approximating the rover’s position if your
position is lost briefly. Off is the default. Fast CPD is generally toggled on when Dynamics is set to Automobile.
GPS (NMEA)
This GPS configuration is typically used to pick up the standard, commonly output NMEA string from a variety of
receivers, including Ashtech MobileMapper CE.
To use the internal GPS of the MobileMapper CE unit, set the following:
Instrument
NMEA GPS Receiver
Communications
Port Number: COM2
Baud Rate: 57600
Parity: None
Char Length: 8
Stop Bits: 1
Configure Reading
Make sure that you toggle off the option to Store Fixed Only.
