Overview

Aviation-Grade GNSS for the eVTOL Revolution

eVTOL aircraft — air taxis, autonomous cargo drones, and urban air mobility platforms — operate at the intersection of aviation safety standards and commercial UAV agility. Their GNSS requirements are uniquely demanding: centimeter RTK accuracy for vertiport approach and landing, RAIM fault detection for autonomous flight safety, and AIM+ anti-jamming to protect against the intentional and unintentional RF interference that saturates urban environments.

Eview GNSS receivers combine Septentrio AIM+ anti-jamming (60 dB suppression), RAIM/FDE (Fault Detection and Exclusion) for signal integrity monitoring, and RTK/PPP accuracy modes — providing the positioning foundation required for certified eVTOL operations.

Applications

eVTOL & Urban Air Mobility Use Cases

From precision vertiport landings to autonomous cargo delivery, Eview GNSS powers the full eVTOL mission profile.

🚁
Urban Air Taxis
Centimeter RTK for vertiport approach, hover, and landing. AIM+ ensures position integrity in RF-dense urban environments alongside 5G towers and radar systems.
📦
Autonomous Cargo eVTOL
Anti-spoofing protection for high-value cargo delivery missions. RAIM fault detection ensures safe mission abort if GNSS integrity degrades below threshold.
🏙️
Urban Air Mobility Corridors
Reliable positioning in the multi-path, high-RF urban environment. Multi-constellation tracking maintains fix geometry even with partial sky obstruction.
⚡
Vertiport Operations
Precision approach and pad positioning for automated vertiport operations. Centimeter accuracy enables tight landing pad tolerances in constrained urban locations.
🔋
Inspection & Patrol eVTOL
AIM+-protected GNSS for eVTOL patrol and inspection platforms operating near power infrastructure — maintaining position where standard GNSS would be jammed.
🌆
Emergency Response eVTOL
Reliable autonomous positioning for medical supply delivery and emergency response UAVs where GNSS integrity and jamming protection are mission-critical.
FAQ

eVTOL GNSS — Frequently Asked Questions

What makes GNSS for eVTOL different from standard UAV GNSS?
eVTOL aircraft face higher safety standards than commercial UAVs — they carry passengers or high-value cargo over populated urban areas. This demands RAIM (Receiver Autonomous Integrity Monitoring) for signal fault detection, anti-spoofing protection against deliberate signal manipulation, AIM+ anti-jamming for urban RF resilience, and higher update rates for flight control. Eview receivers address all four requirements.
What is RAIM and why is it required for eVTOL operations?
RAIM (Receiver Autonomous Integrity Monitoring) is a GNSS self-check algorithm that compares redundant satellite measurements to detect faulty or spoofed signals — without relying on an external reference. For autonomous eVTOL operations over populated areas, RAIM (and its extension FDE — Fault Detection and Exclusion) provides the signal integrity assurance required by aviation safety standards.
How does AIM+ protect eVTOL GNSS in urban environments?
Urban environments combine high-power 5G/LTE transmitters, radar systems, and the growing threat of deliberate GNSS jamming. AIM+ uses active interference cancellation across all GNSS frequency bands simultaneously — suppressing up to 60 dB of jamming while maintaining full RTK positioning. For eVTOL operations in downtown corridors, this means reliable positioning even near the most RF-intense infrastructure.
Can Eview GNSS modules meet aviation weight constraints for eVTOL?
Yes. Eview’s compact OEM board family — including the Mosaic Click and M-2 GNSS Board — weighs under 10g with full RTK, RAIM, and AIM+ capability. These modules are specifically designed for size and weight-constrained platforms where every gram is engineered for purpose.
