Emposat -Space Situation

Space Situation

The full-life space debris early warning service product of the spacecraft will make overall use of various monitoring data resources at home and abroad to escort your spacecraft and other space assets.

Consulting Collision warning Space situation view

In 1983, the Space Shuttle Challenger collided with a tiny piece of 0.2 mm in diameter, which caused damage to its portholes and it had to return to Earth early.
On 24 July, 1996, French Cerise satellite was hit by a catalogued space debris object from an Ariane rocket, causing damage to the satellite's gravity gradient stabilizer bar, and ultimately the satellite lost stability.
On May 24, 2013, the Ecuadorian NEE-01 Pegaso satellite had a side impact over the Indian Ocean with the remains of a rocket fuel tank launched by the former Soviet Union in 1985, leading to the end of the satellite's lifespan.
So far, the International Space Station has carried out 24 maneuver evasions to avoid the impact of space debris, and each time evasion consumes about 30 kg of propellant.
……
In recent years, space collision incidents have occurred frequently. Internationally, satellite maneuvers to avoid debris impact have reached more than 30 times a year, and there have been many satellite anomalies or failures caused by debris impact.

Launch permit application compliance

In view of the space debris mitigation requirements at the launch license application stage,
the compliance of satellites and constellations is analyzed.
Collision risk assessment at the satellite design stage

In the satellite design phase, the planned orbit combined with the distribution of space debris is used to evaluate the long-term collision risk that the satellite will encounter after it enters orbit.
Rocket launch warning

Before the satellite is launched, the collision risk that will be encountered in the short term when launching with different launch windows is evaluated, and a relatively safe launch window will be recommended.
Satellite orbit support at the beginning of its orbit

In the early stage of satellite orbit, combined with the launch information, it will perform non-cooperative measurement and orbit prediction to give the orbit position in the short term in the future for application support such as orbit analysis and TT&C.
On-orbit collision warning

It conducts normalized screening on the space debris collision threat encountered by the satellite during its in-orbit stage. Once a dangerous event is discovered, it will promptly give early warning, accurately assess the collision risk, and give suggestions for avoidance.
Evasion effect evaluation

After the satellites carry out avoidance of dangerous intersections, it will use the new orbit information after avoidance to evaluate and analyze the avoidance effect, summarize the avoidance experience, and guide future avoidance activities.
Emergency track measurement and analysis support

In the event of a satellite failure or other emergency situation, emergency orbit measurement is carried out, and satellites' orbit changes are analyzed and emergency analysis and troubleshooting are supported.
End-of-mission off-track planning and evaluation

After the satellite mission ends, the orbit of the satellite is evaluated and analyzed, and the de-orbit strategy and plan are specified based on the satellite situation. After the satellite is de-orbited, the de-orbit effect and compliance are detected and analyzed.
