DroneX 2026 puts the module layer that decides whether an autonomous platform holds its position in front of the people who build them, and Septentrio’s answer on the booth is the multi-frequency mosaic-G5 P6. The show runs 29–30 September in the United Kingdom, with Septentrio presenting…
An eVTOL GNSS navigation system must deliver four things at once: centimetre RTK position, proven integrity (RAIM+/FDE), immunity to urban RF interference (AIM+), and a fix fast enough for the flight-control loop. Weight is the constraint that makes it hard. You choose between a 14 g integrated receiver, a 60 g 100 Hz board, or…
Why an RTK fix degrades after sunset in low latitudes: ionospheric scintillation, the S4 and sigma-phi indices, and how IONO+ holds accuracy.
RTK accuracy classes for outdoor mobile robots, why consumer GPS fails, dual-antenna heading vs magnetometer, and a module/board/receiver-box spec table for AMR integrators.
A jammer can shift a receiver’s PPS while position stays fixed. Why frequency-dependent delay causes it, and how in-band zero-delay anti-jamming (Septentrio AIM+) prevents it.
What 5G phase sync really requires, how long holdover must last, and which GNSS timing receiver features keep small cells in spec.
Find GNSS interference with the receiver’s own spectrum view, notch it out, then enable WBI wideband mitigation. How AIM+ works in practice. Request a quote.
Assured PNT for critical infrastructure means a network keeps trustworthy position and timing even when GNSS is degraded, jammed or spoofed. That is achieved at the receiver: multi-constellation, multi-frequency GNSS with interference mitigation (Septentrio AIM+), integrity monitoring (RAIM+), continuous interference logging, and a disciplined holdover clock for time-critical systems. Power, water, telecom and transport operators…
RAIM+ rejects bad GNSS measurements before they corrupt your fix. How Septentrio integrity monitoring keeps RTK stable in multipath. Request a quote.
A GNSS compass gives a vessel true heading from two GNSS antennas mounted a fixed distance apart — no spinning mass, no magnetic deviation, and typically a fraction of the cost of a marine gyrocompass. Heading accuracy scales with the antenna baseline: as a rule of thumb, about 0.1–0.2° per metre of separation. What actually…
