GPS Receiver
As determined by factory settings, the Net-960CE-S optionally provides an internal
GPS receiver especially suited for navigation applications and traffic reports.
Serial Port 2 can switch between the internal GPS Receiver and the external SER2
connector (page 28 and 44) upon software request.
The Trimble Lassen iQ module is provided with the following features:
• 12-channel simultaneous operation
• Horizontal Accuracy : <5 meters (50%), <8 meters (90%)
• Altitude Accuracy: <10 meters (50%), <16 meters (90%)
• Supports NMEA 0183, TSIP, TAIP protocols
The GPS Receiver requires an external GPS antenna connection. The GPS antenna
receives the GPS satellite signals and passes them to the GPS Receiver. The GPS
signals are spread spectrum signals in the 1575 MHz range and do not penetrate
conductive or opaque surfaces. Therefore, the antenna must be located outdoors with
a clear view of the sky. For further details, refer to the GPS Antenna Connector
section, page 52.
• The back panel of the Net-960CE-S provides a GPS antenna connector, as
shown on page 16.
Wireless LAN
The Net-960CE-S provides a local area network (IEEE 802.11 standard) that
transmits over the air typically in the 2.4GHz frequency band. Supported protocols
are IEEE 802.11b and IEEE 802.11g.
It does not require line of sight between sender and receiver. Wireless base stations
(access points) are wired to an Ethernet network and transmit a radio frequency over
an area of several hundred feet through walls and other non-metal barriers. Roaming
users can be handed off from one access point to another like a cellular phone system.
