APS-3X

The APS-3X enables seamless GPS+GLONASS RTK operations with either the Integrated GNSS antenna or an External GNSS antenna for maximum flexibility.

The APS-3X incorporates an automated antenna detection capability to switch between internal and external antennas.

While GPS+ GLONASS RTK is delivered in a small and light design for ultra portability, the external GNSS antenna option adds ultra flexibility. RTK surveys may be done with the traditional survey pole, a backpack, or with a vehicle using the same APS-3X receiver to optimize equipment investment.

The APS-3X integrated wireless option 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-3X is completely configurable from the data collector via Bluetooth for either Base or Rover operation with the internal UHF radio, or Network Rover operation with the internal cellular modem.

APS-3X Features

  • 136 Channel GPS + GLONASS receiver
  • External GNSS antenna port
  • 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-3m via Bluetooth for a cable free operation. Furthermore, the APS-3m houses two hot swappable Li-lon batteries for continuous operation. Re-charging is done within a few hours with the included charger.

APS-3X Benefits

Maximum Use

  • High capacity hot swappable Li-Ion batteries for continuous power supply during long work sessions.
  • Choice of Cellular or UHF transmission delivers maximum uptime for RTK, with the ability to change from RTK Network to Base-Rover when 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.

 

GNSS Performance

  • Receiver options for GPS, GLONASS, & SBAS are standard, as well as future compatibility with GALILEO, and BeiDou.
  • RTK performance within minutes from 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

  • Each unit can be a Base or Rover unit with no additional equipment purchase.
  • 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 cellular use.
  • 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.
