Surrey Satellite Technology Ltd (SSTL) is a small satellite manufacturer based in Surrey (UK) known for their company slogan “Changing the Economics of Space” and breakthrough space engineering approach (www.sstl.co.uk ). By purchasing the first Space grade Commercial Off the Shelf (SCOTS) sunsensors, they are to be considered early adopters of this approach which is promoted by Lens R&D. The BiSon64 sunsensors are small but highly reliable sensors specifically developed to provide a low cost alternative to common high reliability sunsensors as well as a high reliability alternative to common small satellite sunsensors. Designed for high reliability and qualified to very rigorous levels, the sensors are to be considered capable of surviving all other equipment’s on board of a common satellite. This is a very desirable property for sensors that are commonly used during early orbit acquisition and safe mode operations only. Being optimised for automated production in larger series the sensors are ideally suited for recurring production and large constellation applications. As of November 2016 it is the intention to keep a minimum level of stock at Lens R&D, thus redefining commercial off the shelf to what the original meaning stands for. Adding to this the fact that the sensors are to be considered true space quality sensors the deliveries deserve the label Space grade Commercial Off the Shelf (SCOTS)
As Lens R&D is batch producing the sunsensors and the team is very limited we decided some years ago to try and sell sunsensors with a minimum order quantity only. Now the sensors will be on stock shortly and with the first sensors shipped, we are getting all the paperwork and procedures in place and concluded that with some additional handling we should be able to deliver one off sensors as well. Therefore, (as a matter of test to see if it really works) we will no longer use the minimum order quantity previously quoted but we will also sell sensors on a one by one basis. In order to compensate for the additional paperwork the price will be marginally increased to 4050Euro/sensor.

Today we received the first titanium housings for the BiSon74ET-RH.
As we already had the 2mm thick sapphire membranes on stock it was quite easy to generate a first impression of what this sensor will look like once completely assembled. Therefore we would like to present a sneak preview of the sensors today.
Designed in frame of an Artes 5.2 contract (for the use on extendable solar panels of Geostationary telecom satellites) and currently under production, the BiSon74ET-RH is a sunsensor that is to exhibit an unprecedented operating temperature range of +125C till -125C in combination with a very high level of radiation tolerance.
At a mass of less than 25 grams and with a 4 by 4 cm mounting pattern, the sensors are small, reliable and by virtue of the batch manufacturing used for all Bison sunsensors very affordable. The wide temperature range in combination with photodiodes that have been tested up till 1.1Mrad and 10^16 1MeV electrons and are shielded by a 2mm thick sapphire window, this sensor is expected to be able to fulfil the environmental requirements for just about any mission.
The field of view is larger than for the normal BiSon64 sunsensors as the sensors were produced with a specific large volume mission in mind, but a BiSon64ET-RH can be developed quite fast and qualified on basis of similarity in majority if required. for information please contact firstname.lastname@example.org or give us a call at +31 71 2020 123
