Altus Presents Latest GNSS Surveying Technology for the 2013 Esri Survey Summit

APS-T and APS-3L are built around a high-precision 136-channel Septentrio GNSS receiver with an embedded L-band modem for receiving differential data from the TERRASTAR-D satellite network. The APS-3L is field-switchable to either RTK or PPP, while the APS-T L-band product can easily be upgraded for RTK when higher accuracy is required.

“The APS-T and APS-3L are designed to provide a low-cost alternative for GNSS surveying in GIS field applications where it is impractical or unnecessary to obtain RTK-level accuracy,” said Neil Vancans, president and CEO of Altus Positioning Systems. “The systems are capable of providing better than 10-cm positioning accuracy without a reference station when gathering data in locations beyond the reach of RTK networks using GSM or UHF frequencies.”

“The L-band solutions are ideal for GNSS surveying in archeology, utilities, agriculture, forestry, oil/gas, mining and construction sites in remote regions and harsh environments,” said Vancans. “The TERRASTAR-D service provides robust performance even in areas of high ionospheric interference.”

TERRASTAR-D is a subscription-based service introduced in 2012 for land-based surveying applications. The TERRASTAR-D network broadcasts on seven independent satellites with overlapping coverage, ensuring that a minimum of two satellites are visible simultaneously at most locations in the world.

The APS-T and APS-3L are the latest evolution in Altus’ product line of surveying instruments based on the popular APS-3 GNSS receiver architecture, which provides interfaces into ESRi tools such as ArcPad using third-party data collection and job management software packages such as MicroSurvey FIELDGenius and Carlson SurvPC, as well as the new GIS360 mobile application for smartphones and tablets.
