When it comes to utilizing L-Band correction services to achieve optimal results for your airborne application, deciding on the best solution can be a tricky endeavor as there are a variety of options available.

Understanding exactly what constitutes success in your specific application will help you with settling on the right one. Start by asking yourself these questions:

  • What’s the level of accuracy I’d like to achieve?
  • Do I need a solution without a convergence period?
  • Will it be working in harsh or benign environmental conditions (e.g. heavy precipitation)?
  • What is the range that I will be working with?

These are only a few of the factors that should be considered. At Blue Planet Geomatics, not only do we offer superior GPS/GNSS products, but we also strive to make it as easy as possible for you to make intelligent decisions.

Airborne Applications Utilizing GNSS and L-Band Correction Services

  • Clear-air turbulence (CAT) studies
  • Aircraft surveillance to communicate an aircraft’s position to ground control centers and other aircraft for traffic information and avoidance (for military, private, and commercial aircraft)
  • Autonomous flying of Unmanned Aerial Vehicles (UAVs) for a wide array of different activities that include, but are not limited to, security (e.g. border patrol), infrastructure surveillance (e.g. power lines), and agriculture (e.g. crop spraying).
  • Aerial surveying to collect geographical information, such as sea levels and vegetation, using airborne vehicles.
  • Airborne remote sensing to capture high-quality images of the Earth’s surface

Positioning Solutions

  • Real Time Kinematic (RTK) 
    • If your aim is to achieve the highest level of accuracy (up to centimeter-level positioning) in the fastest time, RTK is the best correction service for your application. It requires a rover and a base station and/or a communication link to a base station.
  •  Precise Point Positioning (PPP)
    • This method has global availability and will allow you to calculate decimeter-level positioning using only a rover receiver; no other hardware is necessary for its use. It uses a carrier-phase method to make corrections.
  • Differential GNSS (DGNSS)
    • The differential GNSS technique is an enhancement to a primary GNSS system that consists of the determination of the GNSS position for an accurately surveyed position known as a reference or base station.
  • Satellite Based Augmentation Systems (SBAS)
    • SBAS is useful for improving accuracy in situations where rover stations are spread out over a large area. These systems broadcast correction signals from geostationary satellites.

Available Correction Services


 OmniSTAR offers four different DGNSS solutions:

  • OmniSTAR HP
    • Dual frequency receiver needed
    • Local base stations not required
    • 10 cm at 2-sigma (95%)
  • OmniSTAR XP
    • Requires dual frequency receiver
    • Slightly lower level of accuracy than OmniSTAR HP but has global availability
    • Short-term accuracy of 1-2 in
    • Long-term repeatability of 10 cm or better, 95% CEP
  • OmniSTAR G2
    • GLONASS satellites and correction data are included
    • Useful in situations with limited satellite visibility caused by terrain, buildings, and vegetation
    • Short-term accuracy of 1-2in
    • Long-term repeatability of 10 cm or better, 95% CEP
  • OmniSTAR VBS
  • Ideal in situations where repeatability and accuracy are not the primary concerns
  • L1 only, code phase pseudo-range solution
  • Typical 24-hour sample will show a 2-sigma (95%) of significantly less than 1m horizontal position error
  • 3-sigma (99%) horizontal error will be close to 1m


  • RTK: provides accuracy of 1 cm + 1 ppm horizontal and 1 cm vertical (< 40 km baseline range).
  • PPP:
    • NovAtel TerraStar-C is accurate to 4 cm RMS horizontal and 6.5 cm RMS vertical with a convergence time of 20-40 minutes
    • NovAtel TerraStar-L is accurate to 40 cm RMS horizontal and 50 cm RMS vertical with a convergence time of 5 minutes or less
  • DGNSS: provides 40 cm accuracy with a range of up to 100 km
  • SBAS: 60cm accuracy with no initial convergence period and instantaneous re-convergence
