In order to use any third party GPS software, the CG1-RADIO board
must appear to the host CPU as a pair of serial interfaces (UART COM ports).
The available EKF drivers, by interacting with the local on-board i960 firmware,
enforce this behaviour.
Currently, there are
Windows NT 4 / 2000 and Linux drivers
available for download.
The intelligent mode of the CG1-RADIO allows to run user specific
tasks locally, without charging the host system. EKF supports
its customers by offering turn-key ready firmware. EKF recommends
IxWorks (WindRiver) based solutions and tools for its i960
equipped boards, requiring a Tornado development system.
In addition, there are stand-alone tools available, beginning
with the
MON960 monitor.
The Jupiter receiver module communicates likewise using the
Rockwell Binary format
for exchanging commands and data (this is the proprietary way),
or by the
NMEA 0183 ASCII standard
(this is the most common solution). Since the GPS SA (Selective Availability) has been
deactivated, the additional protocol
RTCM SC-104
for sharpening positioning data has lost most of its importance.

The aims of the CG1-RADIO are twofold:
- to get worldwide the accurate time and date for
synchronizing the host system clock
(presumable of importance in any system that is used
to record time stamped
data, or starts scheduled processes)
- to get positioning data (presumable
interesting in mobile systems)
Select the application program that fits your needs best.
The CG1-RADIO can be used together with a wide range of free and
commercial Windows based
software. As a starting point, please visit the site of
Peter Bennett.
Please note that EKF did not test all of the programs mentioned
and therefore cannot be made responsible in case of malfunctioning software.
As a reference, EKF has tested
Map&Guide, a well known
commercial application,
for interaction with the CG1-RADIO under NT 4.
As examples for Linux,
kgps and
gpssync
have been tested by EKF. These are tools for displaying the time data stream
or synchronizing the system
clock by the received GPS UTC time data.
