Septentrio has introduced its next-generation high-precision Altus APS3G RTK receiver, which brings technology only previously available in scientific receivers into the field for professional surveyors.

The new multi-constellation APS3G addresses concerns about compatibility with new satellite constellations, as well as interference and jamming, according to Neil Vancans, vice president of Septentrio Americas. 

“With 544 channels capable of tracking all known and foreseen satellite signals and bands, the all-in-one unit is future proof, and Septentrio’s open architecture makes the APS3G compatible with most other hardware and software solutions, driving down the lifetime cost of ownership,” Vancans says. “In addition, with its extremely low power consumption, no other survey receiver on the market gives as much battery life, saving time and money on the job.”

Built on Septentrio’s AsteRx4 engine, the APS3G tracks all-in-view GPS, GLONASS, Beidou, IRNSS, SBAS, Galileo and QZSS, including E6/L6, and all other signals known to be available in the medium term. The APS3G incorporates Septentrio’s AIM technology with three notch filters for in-band jamming and chirp jammer resistance, ensuring high accuracy and resilience.

With two hot-swappable batteries, the APS3G provides up to 14 hours of operation without recharging, maximizing uptime in the field.

The APS3G provides optimum GSM signal reception, as well as a built-in advanced UHF receiver for reliable performance on longer baselines, yielding real-time 25 Hz RTK. It also supports TERRASTAR L-band corrections for sub decimeter-level accuracy.

The flexible APS3G receiver can function as either a rover or base station, providing maximum versatility in the field.
