Altus APS-3

 

Introducing the APS-3

The APS-3 from Altus Positioning System is a high precision GNSS satellite receiver with integrated state of the art communications designed specifically for the Surveying market.

  • High Productivity
  • High capacity hot swappable batteries mean that power supply can be continous for even the longest working sessions
  • Maximum uptime with the ability to change from GSM/GPRS delivered corrections to UHF radio delivered corrections
  • Data collector software with ease-of-use enabling a fast start for Surveyors with minimal training on product use
  • Performance
  • With the ability to process GPS and Glonass L1, L2, and L2C signals as well as SBAS and L5 if necessary, the APS-3 works with the optimum signal and geometry available creating the most reliable results
  • Fast Acquisition and reacquisiton mean that there is less wating or discontinuity caused by obstructions
  • 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
  • External GNSS antenna or external radio antenna is easily connected
  • The APS-3 can be used with an external CDMA modem
  • Data collector software with ease-of-use enabling a fast start for Surveyors with minimal training on product use
