ADS-B works by having an aircraft's transponder regularly broadcast its position, speed, and identification information to Air Traffic Control (ATC), as well as to other aircraft that have the ability to receive ADS-B data.
A decentralised network of public and private ground-based receivers enables the collection of ADS-B data.
These receivers need to be 'on' and in line of sight in order for accurate location information to be received and transmitted. Obstacles and terrain can reduce the effectiveness of these stations.
See the table below to learn about how Spidertracks and ADS-B technologies work differently.
Satellite-based with Iridium® satellite network
Stay connected to your aircraft regardless of altitude, location or airspace
No black spots or loss of coverage, global connectivity
Consistent broadcast of key flight information and aircraft tracking - no action from the pilot required
No ground structure = no problem, aircraft connectivity is via satellite
Share flight tracks with customers, team members and loved ones - unlimited accounts at no additional cost
Private and secure network, with bank-grade encryption
You own your flight data
Set viewing permissions for different users
Unlimited two-way communication directly with pilots and crew
Real-time notifications, including take-off, landing, excessive ROC / ROD
Built-in emergency framework without the need for pilot interaction
FR24 AFF feed allows for ATC and other FR24 users to see tracking paths
Improved situational awareness - view other aircraft equipped with ADS-B in surrounding airspace
Constant broadcast of flight paths - transmits every second
No action from the pilot required
Collision avoidance - see where other aircraft are
Broadcast an aircraft's position to other aircraft that are also equipped with ADS-B
Flights paths are visible for ATC, other aircraft and the general public
Aircraft must be within range of sight of ground-based receivers to transmit information
Receivers need to be on and in light of sight for information to be received
Terrain and obstacles can limit coverage and effectiveness
No data ownership - your information is available for use by other flight services through public and private receivers
Limited range (approx. 150 nautical miles)
Limited coverage offshore / remote areas
Limited coverage at low altitude ( < 1000ft )
Subject to non-performing equipment (NPE)
By combining ADS-B with the unique benefits of Spidertracks, this will lead to a compliant, safer, and greater operational efficiency for aircraft operators.
For total peace of mind, with no black spots or loss of coverage, we recommend using both ADS-B and Spidertracks in parallel so you can have compete situational awareness, accurate flight tracking, and ensure you and your team get home safely every day.
We wanted to make sure we were tracking our aircraft well. We thought ADS-B [Automatic Dependent Surveillance-Broadcast] would be the magic bullet. Still, we ran into some big issues pretty quickly during training where we didn't see the aircraft. Immediately, we liked Spidertracks for the simplicity of the user interface and how easy it is to get the information we want.
