— For UAV High-Precision Positioning Scenarios — RxTools is the professional configuration and diagnostics software that accompanies Septentrio high-precision GNSS receivers — and an indispensable tool in UAV high-precision positioning system integration. Compared with other GNSS receiver software on the market, four core advantages stand out: native Linux support, integrated spectrum analysis (no external hardware…

Choosing a GNSS antenna comes down to five technical decisions: frequency bands, gain and LNA performance, multipath rejection, form factor, and the interference environment it must survive. A multi-frequency antenna with a clean low-noise amplifier preserves the centimeter-level accuracy your receiver is capable of — while a mismatched or poorly filtered antenna quietly caps the…

Choosing a GNSS receiver for surveying comes down to five technical decisions: accuracy class (RTK, PPK, or PPP), frequency support (dual- vs triple-band), constellation tracking, interference robustness, and field workflow fit. For professional survey work, a multi-frequency, multi-constellation receiver with RTK capability and serious anti-jamming performance delivers reliable centimeter-level results — even near power lines,…

Choosing a GNSS antenna for a UAV comes down to five engineering decisions: frequency bands, radiation pattern, low-noise amplifier (LNA) performance, multipath rejection, and mechanical fit. For RTK drones you need a multi-band active antenna covering L1/L2/L5 with a hemispherical pattern and an LNA that survives the drone’s own RF noise. Get these right and…

Septentrio AIM+ (Advanced Interference Mitigation) protects GNSS receivers by combining hardware and software techniques that detect, characterize, and cancel jamming and spoofing signals before they can corrupt the position solution. AIM+ is built into the receiver’s RF front-end, delivering 40–60 dB of interference suppression — far beyond the ~25 dB typical of consumer receivers like…

A choke ring antenna reduces multipath by surrounding the GNSS antenna element with concentric conductive rings that act as a high-impedance ground plane, attenuating reflected satellite signals arriving from below the horizon. The rings suppress low-elevation multipath by 20–40 dB before it reaches the element — the difference between meter-level code errors and centimeter-level RTK accuracy…

RTK GNSS for Construction Machine Control: Precision Earthmoving Without the Stakes If you are running a heavy civil or site-development operation, you already know the drill: grade stakes every few meters, a survey crew checking cut and fill, and the inevitable rework when the blade goes a couple of centimetres too deep. RTK GNSS for…
