TRITON, or originally called FORMOSAT-7R, is a Taiwanese weather satellite. It can collect sea surface data to derive wind speed using a GNSS reflectometry sensor.[1][2] The English name TRITON comes from the Greek mythology messenger of the sea, Triton.[3]

History

[edit]

The TRITON satellite was originally the FORMOSAT-7R, which was intended to be the indigenous node out of the planned 13 satellites of the constellation FORMOSAT-7. Though, it was decided to be scaled down to one TRITON satellite plus six FORMOSAT-7 satellites.[4]The target of localization is 83%, where AIDC and multiple other domestic participants will together collaborate on the project.[5]

However, despite the goal and claims, it can still be found on the launched missions of Surrey Satellite Technology, indicating it as a product of their company.

It was originally planned for launch amid the start of 2023. However, the rocket Vega C failed during its first commercial launch, so the mission was delayed.[6]

On 14 July 2023, TRITON was transported from Taiwan Space Agency to the airport. It later arrived at Guiana Space Centre. It was planned to launch at Taipei Time 9:36, 5 October.[7]

It was then reported that Arianespace informed the space center that due to the fact that it requires more time to finish the preparation and testing phase, the launch had been further delayed to Taipei Time 9:36, 7 October.[8]

On 7 October, the Vega was heading for launch. However, just 14 seconds before launch, the signal went wrong. Thus, it was further delayed.[9]On 9 October, the mission was restarted and the spacecraft successfully enter orbit.[10]
