altus-productsThe ALTUS approach is simple—design a first-class GNSS positioning system to meet the needs of today’s surveyors and provide the best customer support available. Fully featured and integrated with the latest technology, the APS-3 was created by engineers who have been involved in survey products since the beginning of the satellite surveying era. At ALTUS, we are committed to creating intuitive products with ease-of-use, low cost of ownership and flexibility to accommodate different working environments. Surveyors choose our products over the competition because we’re simply the best—by design.

The APS-3 is a high precision satellite receiver and communications unit specifically designed for the surveying market.

APS-3_0Integrated with state-of-the-art technology, the APS-3 provides surveyors with high productivity, performance and flexibility.

GPS + GLONASS RTK is delivered in a small and light design for ultra portability. The APS-3 has integrated wireless options that include a GSM/GPRS or CDMA modem for easy Real Time Network connection, and a digital UHF transceiver for Base/Rover operation on demand.

For ease of use and simplicity, the APS-3 is completely configurable from the data collector via Bluetooth for either Base or Rover operation with the internal UHF radio, or for Network Rover operation with the internal cellular modem.

APS-3 Features

  • 136 Channel GPS + GLONASS receiver
  • Integrated Quad-Band GSM/GPRS Modem or CDMA Modem
  • Integrated Digital UHF transceiver, 406-470 MHz
  • Integrated Bluetooth
  • Dual Hot-Swap Li-Ion Batteries with Fuel Gauge
  • Removable min.2 GB SD Card storage

With Altus’s open architecture philosophy, the user has the choice of data collector software from MicroSurvey FIELDGenius or Carlson SurvCE to custom software.Rugged field computers are used to communicate with the APS-3 via Bluetooth for a cable free operation. Furthermore, the APS-3 houses two hot swappable Li-lon batteries for continuous operation. Re-charging is done within a few hours with the included charger.


The APS-U provides multi-frequency GNSS capability together with GNSS Heading, L-Band positioning and wireless communications within a rugged MIL-STD-810 housing for the broadest range of applications.

APS-UFor maximum flexibility, the design is scalable from a single GNSS receiver to full options with Heading, wireless links and TERRASTAR L-Band positioning. The APS-U has an additional processor for on-board configuration and custom applications separate from the GNSS engine. The rear panel has an extensive suite of interfaces for data output, timing, event marks, and a second antenna port for GNSS Heading.

Integrated wireless options include Bluetooth® for easy configuration, plus a GSM cellular modem and UHF radio modem for reception of RTK corrections.
