Trimble 4000SSi GPS Receiver
|
 |
The 4000SSi is a full-featured dual frequency GPS receiver ideal for high-end survey applications.
The receiver provides versatile operations for geodetic control, photogrammetry and land movement monitoring.
In addition to using the receiver for postprocessed surveying, the receiver can be used for real-time kinematic
(RTK) GPS surveying and RTCM differential work. The receiver is supplied standard with RTCM input, event
marker input, 1 PPS output, and an NMEA navigation interface. These features allow the receiver to be
used for hydrographic, marine, aerial and everyday survey work.
The display makes it easy to configure settings, create files and locate existing sites when necessary.
The Geodetic Surveyor 4000SSi offers high productivity in many environments traditionally marginal
for GPS. These environments include working in photogrammetric aircraft, under power lines, around
airports and near radio and TV transmitters. With advanced satellite acquisition and tracking, site occupation times are minimized,
the ability to survey near trees is enhanced and down-time due to loss of signal lock is minimal.
