ЦитироватьWith an unexpected new TLE set published, NEXUS now has a slightly better match with object 43940, 2019-003J. Apparently TLEs have not yet stabilized.

ЦитироватьRAPIS-1 Completion of Critical Operations PhaseJanuary 19, 2019 (JST)National Research and Development AgencyJapan Aerospace Exploration Agency (JAXA)JAXA received telemetry data from the Rapid Innovative Payload Demonstration Satellite 1 (RAPIS-1), launched aboard the fourth Epsilon Launch Vehicle (Epilon-4) earlier at 9:50 a.m. (Japan Standard Time, JST), January 18, 2019 from the JAXA Uchinoura Space Center. The RAPIS-1 telemetry confirmed that the satellite's solar panels started generating electricity, which is essential for the RAPIS-1 operation. The telemetry also shows communication with the satellite via ground stations proceeded well. This concludes the critical operations phase. *1RAPIS-1 transitions to the in-orbit checkout phase. *2 During this phase of approximately 30 days, the functions of the satellite's onboard instruments will be evaluated.JAXA conveys deep appreciation for the support by all for the satellite's launch and tracking.*1: The critical operations phase: during this phase that follows the satellite's separation from the launch vehicle, the activities of the satellite's power and communication systems are verified. *2: In-orbit checkout phase: the status of the satellite's entire systems is examined throughout this phase.

Цитировать"RAPIS-1" Successfully Launched and Critical Operation Phase CompletedJanuary 19, 2019Operations Begin for the First Startup-built JAXA satellite"RAPIS-1" (RAPid Innovative payload demonstration Satellite 1), the small satellite commissioned by the Japanese Aerospace eXploration Agency (JAXA) and designed, manufactured and operated by Axelspace Corporation (HQ: Tokyo, Japan; President and CEO: Yuya Nakamura) has been successfully launched from the Uchinoura Space Center in Kagoshima Prefecture, Japan at 9:50 AM of January 18th, 2019. The Epsilon-4 launch vehicle that carried RAPIS-1 to orbit also contained six other microsatellites and cubesats. At 10:42 AM of the same day the satellite was detached from the rocket. Later, a first signal from it was received, confirming that the solar panels—indispensable for the correct operation of the satellite—were producing enough power and that communication with the ground was functional. The operators have thus closed the "critical operation phase" and begun performing check-out operations on all the on-board components. This initial phase is expected to last roughly one month, after which the "nominal operation phase" will begin and the seven experimental instruments will begin performing in-orbit tests.About the Innovative Satellite Technology Demonstration Program and RAPIS-1The Innovative Satellite Technology Demonstration Program is an initiative by JAXA to provide in-orbit validation opportunities to external entities, with the objective of strengthening the technologies behind core satellite components. The Japanese Government's space program has scheduled four demonstration launch opportunities, one every two years. This launch represents the first of these four events and is termed "Innovative Satellite Technology Demonstration-1". RAPIS-1, developed by Axelspace, is a 200kg small satellite carrying seven different demonstration payloads. The mission- and bus-related systems in the satellite are designed to be highly independent, a unique characteristic that increases the reliability of the whole spacecraft to better support the highly experimental onboard components.© JAXAFigure 1：RAPIS-1© JAXAFigure2：rendering of RAPIS-1 and 6 other microsatellites and cubesats installed in the Epsilon rocket (RAPIS-1 is the largest satellite at the top)

ЦитироватьRAPIS-1 Enters Normal Operation PhaseApril 10, 2019Newly introduced, highly automated operation system allows efficient in-orbit demonstration of onboard mission componentsAxelspace Corporation has designed, built and is currently operating RAPIS-1 (RAPid Innovative payload demonstration Satellite 1), launched from the Uchinoura Space Center in Kagoshima, Japan on January 18, 2019 by Japan Aerospace Exploration Agency (JAXA) as part of its "Innovative Satellite Technology Demonstration Program". After completing the in-orbit check-out of all the onboard instruments, RAPIS-1 has completed its initial operation phase and on March 31 it entered its normal operation phase, during which experiments for each of the seven mission components will be carried out.At the same time, the company began operating the satellite with a fully automated operation system that has been recently completed. With this system, the teams responsible for each experimental component can submit mission requests through a dedicated web interface. These requests are automatically converted into an operation schedule and the created commands are transmitted to the satellite. Once an in-orbit experiment is complete, its data is downlinked to the ground station and made available through the same web interface. Unless an anomaly occurs, no human intervention is necessary in any of the above steps. Thanks to this level of automation, Axelspace is able not only to improve the reliability of operation by removing human errors, but also to reduce the running costs of the mission. Figure 1 shows a diagram of the RAPIS-1 operation system.Fig. 1: RAPIS-1 Operation System
