Description:

GPS25PM.EXE is designed to interface with a Garmin GPS 25 XL or GPS 25LP sensor boards and the GPS 35LP sensors. The program will perform the following functions:

-display and log phase data output by GPS sensors.

-upload almanac, position, and time information.

-download almanac and ephemeris information.

GPS25PM.EXE is a DOS based program and will run on IBM 80286 or greater compatible PCs.

Displayed Information:

The GPS25PM.EXE display page is divided into 3 sections. The top-most section contains the following information updated at once a second:

A.Position

1.WGS 84 Latitude, Longitude (degrees - minutes) - 0.0001 minute resolution.

2.Ellipsoid Altitude (meters) - 1 meter resolution.

B.Velocity

1.Each of 3 axis (meters per second) - 0.01 m/s resolution.

2.Altitude (meters/minute) - 1 mt/m resolution.

3.Ground Speed (kilometers/hour) - 0.1 km/h resolution

C.Estimated Position Error - Vertical, Horizontal, Total (meters) - 1 meter resolution

D.Track - (0 - 359 degrees) - 0.1 degree resolution

E.Time

1.GPS time (hours - minutes - seconds) - 1 sec. resolution (not leap second corrected)

2.Receiver Time of Week (GPS seconds) - 0.00000001 sec. resolution.

The middle section contains receiver measurement information for satellites which the GPS sensor is currently tracking. This information is updated once at second:

A Satellite Number (1 - 32)

B. Signal to Noise Ratio (dbHz) - 1 dbHz resolution.

C. Phase (0 - 359 degrees) - 0.1 degree resolution.

D. Pseudo Range (meters) - 1 meter resolution.

E. Accumulated Cycles (cycles) - 1 cycle resolution.
