Astrid Kjeldal
Sales Manager & Team Lead
When working on the commercialization of space, it is essential to make the procurement process as easy and uncomplicated as possible, and this is where satsearch offers an excellent marketplace for the space industry and helps give a great overview for the customer of what the market has to offer.
As a satellite supplier and a satsearch partner, we have had many sales inquiries through satsearch, many of whom are our customers today.
Alberto Ordaz Acero
BD Manager
Satsearch is a must for satellite products and services suppliers to showcase their catalogue effectively, resulting in increased visibility and sales opportunities.
The great team behind satsearch also helps connecting with a global network of potential customers and bringing great monthly reports.
Thomas Yen
CEO
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.

Searching for a CCSDS-compatible S-band transceivers.
Uplink shall comply to CCSDS 231.0-B-4 & 232.0-B-4. For channel coding, only BCH coding is required. BCH may operate in checksum mode (ie: SECDED mode is not required). If part of the framing layer needs to be implemented on the customer side, that is acceptable, as long as the unit at minimum extracts transfer frames. Uplink data rate up to 100 kbps.
Downlink shall comply to CCSDS 131.0-B-6 & 132.0-B-3. For channel coding, 1/2 rate convolutional coding + RS(255,233) w/interleaving is required. If part of the framing layer needs to be implemented on the customer side, that is acceptable, as long as the unit can consume transfer frames. Downlink data rate up to 1 Mbps.
TID hardening is not required, but the system shall be resilient to SEEs (ie: SEU, SEL) up to 600 km.
Looking to procure 5 EMs & 5 FMs. If the unit operates satisfactorily, this may lead to a long-term engagement of 5-10 FMs/year starting in 2030.
