Your AmbaSat-1 satellite, also known as a CHIPSAT, will travel into space inside the AmbaSat 3U CubeSat which is secured inside the launch rocket. The CubeSat is a rectangular structure which measures approximately 10cm x 10cm x 34cm. Inside the 3U container, there are up to 25 ‘Flight Trays’, with each carrying eight AmbaSat-1 Space Satellites.
On reaching Low Earth Orbit, around 300 km – 500 km above the earth, the rocket will deploy the AmbaSat 3U CubeSat or hosted payload. A radio transmission will then be sent from our ground station with the command to wake up the AmbaSat Mission Control Computer and begin powering the AmbaSat-1 Satellites. From this point, you will start to receive telemetry and sensor data will be transmitted to your AmbaSat Dashboard.
The CubeSat can hold up to 200 AmbaSats and transports them into Low Earth Orbit (LEO)
At an altitude of about 300 km, the container and AmbaSats spend about one month in LEO
Over 20,000 radio ground stations spread right across the world listen for AmbaSat telemetry
Hosted payload launches are scheduled for 2023, with UK launches following
Skyrora XL is a three stage launch vehicle intended to place payloads between 200km and 1,000km altitudes
Skyrora XL stands 22.7 meters tall with a total lift-off mass in excess of 55,000 kilograms
An encapsulated payload module with push-rod springs that will deploy the AmbaSat Container to LEO
Your AmbaSat-1 Space Satellite, known as a CHIPSAT or femtosat class of satellite, measures 35 x 35 x 5 mm. Eight satellites fit on a stackable ‘Flight Tray’, and a stack of 25 trays fits inside the AmbaSat 3U CubeSat which equates to 200 satellites per launch. Each satellite remains inside the container for the duration of the mission.
Due to licensing constraints, the chipsats will remain inside the 3U CubeSat for the duration of the mission. The open-case design of the 3U means that all AmbaSats will function in exactly the same manner as if they were in free flight. An additional benefit of this design is that power requirements and radio communications will be supported by the 3U CubeSat.
A hosted or shared payload is one where the AmbaSat CubeSat is hosted as part of another satellite deployment. This has a number of advantages which include no licence requirements, the supply of host power and comms systems, and more cost-effective launches. We are currently in negotiations with a number of providers regarding hosted payload missions. Concurrently, we are also applying for our CAA licence to allow AmbaSats to be deployed.
Whether you are an individual, business or educational establishment, the process is the same: Once you have assembled your satellite, programmed it and fully tested it using our Quality Control test procedures which are documented as part of the kit, you must then wait for notification of your rocket launch schedule. Launch slots are allocated during the purchase of the satellite kit. Once we are notified of the rocket launch schedule, there is a 3 – 6 month period where you return your satellite to AmbaSat, where it will undergo final tests before being mounted inside the 3U Container.
On launch day, we aim to provide a live stream of the rocket launch. Once the CubeSat is deployed into Low Earth Orbit, telemetry data from your AmbaSat will be received via the Dashboard. Radio signals will be sent using LoRaWAN which makes use of the 20,000+ ground stations of ‘The Things Network’. In addition and as a backup, telemetry data will also be transmitted via UHF-Band to the AmbaSat Ground Station.
In a Deployed Payload Scenario, your AmbaSat mission will continue for ONE month before the 3U CubeSat and AmbaSats re-enter the earth’s atmosphere where they will burn up with very little environmental impact. For hosted missions, the duration is dependent on the host.
In a deployed scenario, we will enter a polar orbit with an inclination of 80-90 degrees. Apogee will be approximately 280km. Please contact us if you would like full technical details.
