Can RTK hold a fixed solution under tree canopy in the rain? A review of 36 screenshots from a multi-receiver field test with Septentrio mosaic-X5 and mosaic-H platforms (Eview HB56 / HB56H), with fix ratios, limits and a retest design.
Measured PVT output latency, jitter and update rate across seven receivers: 4.41–4.73 ms average latency, 0.97–1.5 ms jitter and up to 100 Hz output on the Eview HB56, built on the Septentrio mosaic-X5.
To get the right GNSS receiver quote, your RFQ must specify four things that change price the most: accuracy class (RTK centimetre-level versus sub-metre), form factor (OEM board or enclosed receiver box), interference environment (clean sky or RF-dense — this decides whether you need AIM+ anti-jamming), and quantity. Send those four and a vendor can…
GNSS structural monitoring tracks millimetre-level movement of bridges, dams, slopes and tall buildings continuously and in real time. Permanently installed multi-frequency receivers measure their own 3D position against a stable reference station and report X/Y/Z displacement 24/7, in all weather. A typical network samples at 1–20 Hz and resolves millimetre-level change — something periodic total-station…
Image credit: Septentrio — DroneX 2026 event banner (septentrio.com). 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.
