Orbit Logic reports NASA has selected the company's STK Scheduler software for the Restore-L technology demonstration mission. During its mission, the Restore-L spacecraft will demonstrate the technologies required to rendezvous with, grasp, refuel and relocate a government-owned satellite.
Restore-L chose an Orbit Logic solution because STK Scheduler's timing and event constraint checking, along with its auto-sequencing features, will provide NASA with an adaptable, invaluable tool to perform Restore-L's highly complex mission timeline and sequencing.
Restore-L is a technology demonstration mission planned by NASA for the in-orbit servicing and refueling of a satellite not designed to be serviced. The project is currently in formulation and planned for launch in 2022.
Given that Restore-L is both complex in its rendezvous and servicing tasks, and is being executed in low-Earth orbit, schedule visibility for radio frequency (RF) communications is critical to mission success.
Strict rulesets and mission constraints, coupled with RF communications, must be cross-referenced for specific servicing tasks and approach sequences.
STK Scheduler supports the configuration and implementation of all Restore-L scheduling constraints out-of-the-box, allowing for quick initial deployment, testing, and use in pre-launch planning, simulations, and on-orbit mission execution at a fraction of the cost of custom software development.
NASA's Restore-L project is an ambitious, technology-rich endeavor to launch a robotic spacecraft to refuel a live satellite.
Restore-L, named to highlight how robotic servicing capabilities can return a satellite to its original proficiency, is a spacecraft equipped with the tools, technologies and techniques needed to extend satellites' lifespans - even those not originally designed to be serviced in orbit.
The technology demonstration mission - the first of its kind in low-Earth orbit - will demonstrate a carefully curated suite of satellite servicing technologies. These in-orbit solutions for autonomous satellite rendezvous and grasping, with telerobotic-enabled refueling and satellite repositioning, could make spaceflight more sustainable, affordable and resilient.
Bursting the clouds for better communication
Geneva, Switzerland (SPX) Oct 19, 2018
We live in an age of long-range information, transmitted either by underground optical fibre or by radio frequency from satellites. But the throughput today is so great that radio frequency is no longer enough in itself. Research is turning towards the use of lasers which, although technically complex, have several advantages, especially when it comes to security. However, this new technology - currently in the testing phase - faces a major problem: clouds. Due to their density, clouds stop the la ... read more
