We have worked with satsearch since the early days of Tensor Tech and it has always been an important partner for us.
Unlike how sales traditionally works in the space industry, satsearch provides a transparent way for buyers to look for suitable suppliers and products.
I believe they have truly fostered the growth of the industry.
Tensor Tech, as a user, has also enjoyed the way we update our information, monitor the traffic for data analysis, and attract more international clients.
Ronnie Nader
Chief Designer and Director of Space Operations
Ever since we signed up for satsearch back in 2019 it was an immediate hit and it has been a game changer for us.
The people involved really want their users to succeed, they do understand the industry and the market and not only that, but for providers, the relationship has been a constant feedback about what works and what does not, who is who in the landscape and all that knowledge serves to improve the platform and the quality of the leads.
We also have other leads providers, so we can compare, and none gets to the level of satsearch. In short, satsearch works, period.
Struan Johnston
Director
It has become a well known supply chain platform for the industry and a great place to find and compare different suppliers in a fraction of the time.
As a manufacturer of satellite components, we have grown our reach and audience using satsearch as a marketing channel, and met many of our customers via satsearch for the first time.

We are seeking a complete ADCS solution for a 3U CubeSat Earth-observation mission scheduled for launch in Q1 2027. The ADCS must provide attitude determination and control suitable for a 3U platform operating in a 550 km sun-synchronous orbit (approximately 97.5° inclination).
The system should include the required ADCS hardware, sensors, actuators, electronics, flight software, and associated accessories required for integration into the satellite. We are particularly interested in a ADCS solution compatible with our 3U satellite architecture and capable of supporting detumbling, three-axis attitude determination and control, nadir pointing, and attitude stabilization during payload operations. The ADCS must have a GNSS as well.
The required performance includes a pointing accuracy of better than 1° (3σ), attitude knowledge better than 0.07°, and adequate attitude stability for multispectral Earth-observation imaging. The system should support integration with our onboard computer, and provide the necessary electrical, mechanical, software, and communication interfaces.
Please provide a complete technical and commercial proposal, including the recommended configuration, system specifications, interface requirements, integration requirements, software and licensing details, delivery schedule, and any additional components required for a complete flight-ready ADCS.
Schedule is critical: the satellite assembly must be completed no later than 30 December 2026, with launch planned for Q1 2027. Suppliers should therefore clearly state the earliest achievable delivery date and total lead time, including manufacturing, testing, and any required integration support.
Summary:
Payload:
Multispectral imager (VNIR, usually 4 to 7 bands, e.g. Blue, Green, Red, Red Edge, NIR), CMOS push-broom or snapshot
Attitude determination (ADCS):

Magnetometer (3-axis)
Gyroscope / IMU (3-axis MEMS)
Star tracker (needed for decent pointing accuracy when imaging)
Earth sensor
Reaction wheels (pyramidal)
