Retrospectively entered on 24 September 2026. Timeline date: 4 September, when the development was reported. Initial customer trials reportedly began in August.

What happened

On 4 September 2026, Militarnyi reported an interview with IKS Holding chief executive Alexey Shelobkov in which he said Bureau 1440 had begun testing Rassvet terminals with prospective customers in August. A mobile terminal intended to operate at speeds of up to 400 km/h was expected to undergo testing on a moving Russian Railways train.

Evidence and limitations

This is a reported company statement about trials and a planned test, not independent verification that the train trial had already been completed or that a stable connection was maintained at 400 km/h. Reported customer access does not establish general commercial availability.

Assessment

Moving-platform trials are relevant to terminal engineering, tracking and handover between satellites. The test results, not the advertised design speed, will determine the significance of this milestone.

Why it matters

Rassvet’s practical utility depends on the ground segment and mobile user equipment as much as the number of satellites in orbit.
