APS-3

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

Integrated 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.

APS-3 Benefits

High Productivity

  • High capacity hot swappable batteries mean that power supply can be continous for even the longest working sessions
  • Choice of Cellular or UHF transmission delivers maximum uptime for RTK with the ability to change as required by field conditions
  • Data collector software with intuitive ease-of-use enables a fast start for Surveyors with minimal training on product use
  • Lightweight and compact unit designed for ultra portability.

 

Performance

  • Receiver options for GPS, GLONASS, & SBAS are standard, as well as future compatibility with GALILEO, and Compass ready
  • RTK performance within minutes from easy cable free operation with wireless devices completely integrated into a compact system
  • RTK accuracy at 1 cm + 1ppm or post processing at 2mm + 0.5 ppm

 

Flexibility

  • Base-Rover, Rover-Base it's all the same to the APS-3. Each unit can be a base or rover unit with no additional equipment to buy
  • Internal Digital UHF transceiver programmable over full UHF band 406-470 MHz
  • Compatible with Pacific Crest, Satel, and Trimble radio protocols
  • Quad-band GSM module for worldwide use or a CDMA module option
  • Use the same equipment for pole, vehicle or in-building by connecting an external GNSS antenna
  • Connect an external radio for greater base transmit power or use the external radio as a cable free repeater
  • Removable SD Card enables plug and play raw data transfer for post processing
  • External DC power input for continuous operation
