Our Engineering process

Requirements, analysis, measurement, and reporting

We'll build the scope of work around the test event or milestone and the evidence needed to support it.

01

Define requirements

Document the system, operating environment, acceptance criteria, assumptions, and decision thresholds.

02

Perform the analysis

Apply the RF, electromagnetic, spectrum, or supply-chain methods appropriate to the technical risk.

03

Correlate evidence

Compare predictions with measurements or production evidence when included in the scope.

04

Report findings

Deliver the technical basis, ranked risks, mitigations, limitations, and recommended next actions.

Multi-vehicle RF planning

Planning for one-to-N UAS networks

We'll model the complete RF network to include ground-station radios, UAS, cell to each vehicle and between relay nodes. Terrain, altitude, antenna patterns, radio settings, traffic demand, and measured spectrum conditions are evaluated together using ITU propagation models.

UAS mesh network connecting a ground station to multiple unmanned aircraft across varied terrain.
Multi-UAS network configuration
Link geometry Routes, vehicle altitude, ground-station location, antenna height and pattern, and relay placement.
Capacity and loading Per-link data rate, occupied bandwidth, duty cycle, simultaneous traffic, and protocol overhead.
Interference control Co-channel and adjacent-channel conflicts, near-far effects, receiver desensitization, and frequency-distance separation.
Frequency plan Candidate authorized channels, bandwidths, hop sets, power levels, antennas, and primary/alternate/contingency settings.

Before and during the event

The pre-event study produces a technically viable configuration and alternatives. On event day, measured occupancy can be compared with the model and the plan adjusted within the equipment limits and available authorization.

  • Coverage, link-margin, and capacity analysis
  • Candidate frequency, bandwidth, and hop-set plan
  • Antenna, height, power, and relay recommendations
  • Frequency matrix, map layers, run cards, and incident log
