Palmer Station GPS Survey System - Available Equipment

Equipment Available

A geodetic system consisting of dual-frequency base station and roving receivers, capable of centimeter-level accuracy, is available at Palmer Station. A computer is also available for data downloading and processing at the IMS (TerraLab) facility.

Centimeter-level accuracy can be realized over 100 kilometers away from the station by collecting and post-processing data. Also, real-time kinematic (RTK) broadcasts provide real-time capability within a five kilometer radius of Palmer Station. The RTK signal is broadcast at 470 MHz, with CMR+ format at 9600 baud. A portable RTK repeater is also provided for areas that are within range for RTK solutions but beyond line of sight from Palmer Station.

Base station data (low-rate) are available online from the GAGE Archive (site PAL2). During the austral summer season high-rate data files are downloaded and archived by GAGE, however in general the higher sample rate data are recorded on the receiver only and are not archived. Due to the limited storage space for high-rate data on the receiver, any group requiring high-rate GPS data from this station should make a formal request as soon as possible by emailing

The following GPS equipment is available for use at Palmer Station:
Trimble NetR8 Base Station
Geodetic GPS base station for data collection and RTK broadcasting. An equipment inventory is maintained on this page.
Trimble R7 Roving System
Geodetic GPS system that provides centimeter accuracy in real-time (RTK) or through data collection and post-processing. An equipment inventory is maintained on this page.
Data Processing Computer
A shared computer with Trimble Business Center data processing software and other GPS utilities.
