VFD Menus Chapter 5
MPC User Manual Rev 0D 43
The information in this column is refreshed every second unless another column in the menus is being
edited. The 1 second refresh will continue once the editing has stopped. As seen from Figure 37 on
Page 42, there are several STATUS functionality categories:
• MPC SYSTEM STATUS
• TIME: The current GMT time in hours, minutes and seconds. The time is
the PC time, which is steered by GPS.
• DATE: The current GPS week and seconds into the week once the
GPSCard has a valid solution and is connected.
• GPS: On start-up, ‘NOT CONNECTED’ will be displayed until the
GPSCard is connected. Then information on any GPS receiver system
errors detected are displayed. When there are no errors, there is a ‘GPS
SYSTEM OK’ message.
• EXT OSC: Displays either ‘LOCKED’ or ‘NOT LOCKED’ depending
on if the oscillator in use has achieved lock or not respectively.
• LOGGING: Shows if the logging of GPS data is currently ‘ACTIVE’ or
‘NOT ACTIVE’.
• SPACE: Provides the available recording space left on the MPC hard
drive in megabytes (mB).
• COMPUTER: Shows the name given to the MPC. See Configure
Ethernet on Page 46 where the computer name can be edited.
• MPC POSITION INFO
• POS TYPE: Current position mode:
• NO POSITION: There is no current position mode.
• FIXED POSITION: The position has been fixed.
• SINGLE POINT: The position is from single-point averaging.
• PSR DIFF POS: The position measurement is from
pseudorandom code on the GPS signals.
• L1_FLOAT: The position is from floating ambiguity estimates
that converge over time.
• ION FREE FLOAT:
• NARROW FLOAT:
• L1 INTEGER: The position is from carrier phase ambiguity
estimates that are only allowed to take on integer values.
• WIDE INTEGER:
• NARROW INTEGER:
• LAT: The current latitude in degrees, minutes, seconds and decimal
seconds to 4 decimal places.
