Appendix B
Specifications
This TPS product is a 50-channel GPS receiver integrated with an internal computer and Windows
Mobile6.0 operating system with touch screen, a digital camera, a Bluetooth® wireless technology
module, cellular module (Option),an electronic compass, and an SD card slot. The portable design and
product integration allows this device to be a fully-functional, productive tool at any job.
Performance specifications assume a minimum of 6
GPS satellites above 15 degrees in elevation and
adherence to the procedures recommended in this
manual.
In areas of high multipath, during periods of large
PDOP, and during periods of increased ionospheric
activity, performance may degrade.
Use robust checking procedures in areas of extreme
multipath or under dense foliage.
