Pacific Crest Introduces Advanced Data Link for Field Communications
November 23, 2011
SUNNYVALE, Calif. – Pacific Crest, a Trimble company,
introduced the new ADL Uplink, an advanced, high-speed, wireless data link that
extends the range and improves the reliability of Internet-based RTK
corrections. The ADL Uplink provides
high accuracy and application flexibility with more features and options than
previously offered by Pacific Crest professional-grade radio links.
The ADL Uplink joins the rapidly growing
line of Advanced Data Link (ADL) products that include: the ADL Vantage Pro, a
35-Watt programmable UHF radio; the ADL Vantage, a 4-Watt programmable UHF
radio for survey applications; the ADL Sentry, a 4-Watt radio for remote
sensing and monitoring environments; the ADL Foundation, a transceiver OEM
board; and the ADL RXO, a receive-only OEM board.
“The ADL Uplink is designed for easy
integration with existing systems,” said Dale Hermann, sales and marketing
director for Pacific Crest. “Interoperability
and flexible features can enable
our customers to cost-effectively
deploy the ADL Uplink into their products and solutions.”
The ADL Uplink combines a ruggedized handheld
computer with a software program
that automatically downloads Internet-based RTK corrections and streams them to
a radio for rebroadcast into areas of poor cell coverage. Positioning the ADL
Uplink on the edge of Internet access allows users to continue surveying in
cellular shadow zones caused by topography, buildings or interference where
poor signal strength normally makes using Internet-based RTK services
difficult.
The ADL
Uplink connects to an RTK correction service either through the GSM/GPRS or
Wi-Fi modem. The ADL Uplink provides the service with either coordinates from
its on-board GPS receiver or with coordinates input manually by the user from
the GPS rover receiver. When the corrections are generated, the ADL Uplink
streams the signals from the Internet to a radio for broadcasting to the rover.
Reconnection in the event of a dropped wireless connection is automatic.
