GPS OPERATION
5-4
GPS position data has two transmit modes, D-PRS
and NMEA. Moreover, with the D-PRS mode data,
five position formats, Position (Mobile station/Base
station), Object, Item and Weather, are selectable.
NMEA
D-PRS
Position (Mobile)
Item
Position (Base)
Object
Weather
•D-PRS: D-PRS is a function which simultaneously
sends position data received from the
internal or external GPS receiver, using the
slow speed data packet space, along with
voice.
•Mobile: A station operating from a vehicle, a
vessel, or other location, away from it's
normal base location.
•Base:
A station operating at home or in any
building.
•Object: Transmitting Object data such as an
earthquake information, satellite track
information, and so on.
An Object contains a time stamp.
•
Item:
Transmitting Item data such as a traffic
accident, lighthouse, antenna, or DV
access point location, and so on.
An Item does not contain a time stamp.
•Weather: A station transmitting a weather information
received from the weather device.
•NMEA: A station transmitting position data
(NMEA0183) received from the internal or
an external GPS receiver.
TIP:
For users who have a D-STAR transceiver
model prior to the ID-4100A/E:
The GPS TX mode, “GPS (DV-G)” and “GPS-A (DV-
A),” are now called “NMEA” and “D-PRS.”
