Overview

The SkyHub Software Package for True Terrain Following enables high-precision, real-time AGL altitude control using a connected radar or laser altimeter — not pre-loaded elevation models. By continuously reading live surface distance and adjusting UAV altitude in real time, it maintains a precise, consistent ground clearance over complex, variable, or unmapped terrain. Essential for GPR, magnetometer, and other proximity-sensitive survey payloads where sensor-to-surface distance directly determines data quality.

Real Terrain. Real Time. Exact Altitude.
Unlike GPS-based terrain following that depends on pre-loaded DEM/DSM accuracy, the SkyHub TTF software reads live altitude data from a connected radar (24 GHz) or laser altimeter and continuously adjusts UAV flight altitude to maintain a precise, user-defined AGL distance above the actual surface — in real time, throughout the entire mission. The result is consistent sensor-to-surface distance over hills, slopes, vegetation, and unmapped terrain, enabling safe low-altitude operations and survey-grade data quality for GPR, magnetometer, echo sounder, and other proximity-sensitive payloads. Compatible with DJI M300/M350 RTK and Pixhawk/ArduCopter platforms.

Radar or Laser Altimeter. Your Choice. The TTF package supports both radar (24 GHz) and laser altimeter types — radar for high reliability across diverse terrain and vegetation, laser for regulatory simplicity in any country. Select the altimeter that matches your operational environment and compliance requirements.

Consistent Sensor Distance. Better Survey Data. For GPR, magnetometer, and other proximity-sensitive payloads, sensor-to-surface distance directly determines data quality. TTF eliminates altitude variation caused by terrain changes — delivering the consistent ground clearance that high-quality subsurface and geophysical survey data demands.

UgCS-Integrated. Mission-Ready. The SkyHub TTF software integrates seamlessly with UgCS ground control software for mission planning, real-time altitude monitoring, and automated terrain-following execution — with full compatibility for DJI M300/M350 RTK and Pixhawk-based ArduCopter platforms.

The SkyHub Software Package for True Terrain Following (TTF) by SPH Engineering enables high-precision, low-altitude terrain following using a real-time altimeter sensor — radar or laser — integrated with the SkyHub onboard computer. Unlike GPS-based terrain following that relies on pre-loaded elevation models, TTF measures actual ground clearance in real time, maintaining a precise, consistent AGL altitude over complex, variable, or unmapped terrain.

How It Works

The SkyHub TTF software reads live altitude data from a connected radar or laser altimeter and continuously adjusts the UAV's flight altitude to maintain a constant, user-defined distance above the actual surface below — regardless of terrain variation, vegetation height, or elevation model accuracy. This enables safe, consistent low-altitude operations over terrain that would otherwise require conservative altitude buffers or manual intervention.

Supported Altimeter Types

  • Radar Altimeter (24 GHz) — High reliability over diverse surfaces including vegetation, soil, and uneven terrain; regulatory approval required in some countries (operator's responsibility to verify local regulations)
  • Laser Altimeter — Usable in any country; performance may be reduced over highly reflective surfaces such as water, ice, snow, and sand under bright sunlight

Key Benefits

  • Real-Time Surface Tracking — Continuous AGL altitude adjustment based on live altimeter readings, not pre-loaded DEM/DSM data
  • Consistent Sensor-to-Surface Distance — Critical for GPR, magnetometer, echo sounder, and other proximity-sensitive survey payloads
  • Safe Low-Altitude Operations — Enables confident flight at low AGL over complex terrain without manual altitude management
  • UgCS Integration — Works seamlessly with UgCS ground control software for mission planning and real-time monitoring

Supported Drones & Autopilots

  • DJI M350 RTK
  • DJI M300 RTK
  • Pixhawk-compatible autopilots (Cube and equivalents) running ArduCopter firmware

Requirements

  • SPH Engineering SkyHub onboard computer hardware (required)
  • SkyHub Core Software Package (required)
  • Compatible radar or laser altimeter (sold separately)
  • UgCS ground control software license (required)

Important Notes

  • Radar altimeter (24 GHz): operators are responsible for verifying regulatory approval for use in their country
  • Laser altimeter: reliable over most surfaces; reduced performance over water, ice, snow, and highly reflective surfaces in bright sunlight
  • New customers are recommended to order a complete combo package including software, hardware, and training
