Extending satellites useful life (positioning)
(Beyond “all electric” satellites)
I am sad to inform that my friend John Roach passed away on February 24, 2022 John was a contributor to this project with his knowledge and encouragement.
And a very good person
I will miss him
The importance of extending a satellite’s usefulness is quite straightforward, satellites are very expensive.
A satellite can cost around US$ 300 million (spy satellites are often more expensive) and US$ 80 million to US$ 400 million to place in orbit, therefore prolonging the satellite’s useful life increases chance of a reasonable return on the investment.
Satellites (especially spy satellites) occasionally need to modify their position, they do this by using small thrusters (Fig 1) that use fuel/propellant, when the propellant tank is empty the satellite is stuck in its position and cannot make even minor corrections necessary for operation.
Many newer (so called “all electric satellites”) use electrical thrusters (ion or others Fig 2) that offer LESS thrust but a greater fuel efficiency permitting a longer useful life.
We offer the use of fluid thrusters (Fig 3) that create more thrust (28 millinewtons) than most ion drives and longer useful life as it does not expel propellant.
With the advantage going to the Fluid Drive, this is especially true when it comes to reconnaissance satellites
