E] Event Marker - ashtech GG Surveyor Reference Manual

[E] Event Marker

The [E] option allows the output of a time trigger message (TTT) corresponding to
the time event created by a trigger signal. The event marker is activated at the rising
edge of the trigger signal by default, but can be set to respond to the falling edge on
command.
[G] Geoid Height
The [G] option uses a geoid model to compute orthometric elevation information.
[M] Magnetic Variation
The [M] option uses magnetic variation table.
[J] Phase Differential Mode
The [J] option allows the receiver to use the carrier phase differential (RTCM
message 18 and 19) data for RTK. Both the [B] and [J] options must be enabled to
generate type 18 and 19 messages from a base station. Both the [V] and [J] options
must be enabled to use type 18 and 18 messages at a remote station.
[C] Strobe Correlator
The [C] option enables the use of the strobe correlator in position computation. If this
option is installed, then the receiver uses the strobe correlator by default over the edge
correlator.
[S] GLONASS
The [S] option enables the tracking and use of GLONASS satellites.
