The short answer is, Viasat-3 is now in orbit above the earth. It’s a busy time for this extraordinary communications satellite. Let’s take a look at what’s happening now.

Viasat-3 was successfully launched at 8:26 p.m. EDT on May 1 2023 aboard a SpaceX Falcon Heavy from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida.

About four hours and thirty-two minutes after the launch, the satellite successfully detached from the launch vehicle. Roughly 15 minutes later, the first signals from the satellite were received through a ground station located in South Korea. Over the next few days, ViaSat-3 unfurled its solar arrays and gradually maneuvered to its designated orbital position. It took approximately three weeks for ViaSat-3 to reach its ultimate orbital destination, situated at a longitude of 88.9° west.

In-orbit testing will verify the performance of systems and components in space. This may involve checking communication links, power systems, propulsion, thermal control, and other critical functions. The payload is being tested for functionality, data transmission capabilities, image quality, and overall performance. Communication systems are thoroughly tested to ensure proper connectivity and signal strength. Ground stations establish communication links with the satellite to verify data transmission and reception.

The satellite's power systems, including solar arrays and batteries, are assessed to ensure they are generating and storing sufficient energy to sustain satellite operations. Attitude and Orbit Control System (AOCS) testing will confirm the accuracy and responsiveness of orientation and orbit. Any necessary adjustments to position, pointing accuracy, and stability can be addressed.

Comprehensive tests are also performed to validate interactions between different subsystems and ground control stations. This ensures seamless integration and smooth operation of the entire satellite system.

Performance Optimization: During the testing phase, adjustments and fine-tuning may be made to optimize the satellite's performance, such as antenna alignment, power management, or software updates.

These procedures validate the satellite's functionality, performance, and operational readiness in space. The extraordinary Viasat-3 satellite is expected to go operational toward the end of summer 2023.
