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.

are looking for on satsearch right now
We are looking for suitable S-band transceiver/transponder options for a CubeSat communication subsystem.
The unit should be suitable for a CubeSat mission and support S-band communication with two wideband full-duplex S-band antennas. We are exploring an antenna-selection architecture where the communication subsystem can select the antenna with better received-link quality during operation.
S-band uplink and downlink capability suitable for CubeSat TT&C / data communication.
Full-duplex operation preferred, or clear details on supported half-duplex/full-duplex modes.
Compatibility with two wideband S-band antennas.
Support for single-antenna and/or dual-antenna configuration.
Ability to support antenna selection using either:
1. internal RF switching,
2. transceiver-controlled external RF switch,
3. configurable GPIO / antenna-select output, or
4. OBC-controlled external RF switch.
Ability for the OBC to read RX QoS metrics and command antenna selection, if supported.
Clear RF interface information:
1. single common RF antenna port or separate TX/RX RF ports,
2. RF connector type,
3. output power,
4. receiver sensitivity,
5. required duplexer/diplexer/filtering, if any.
OBC interface details: UART, SPI, CAN, RS-422, RS-485, or other supported digital interface,
Flight heritage, qualification status, environmental test levels, and radiation information.
Availability of engineering model, qualification model, and flight model units.
Current lead time, approximate cost, and procurement options.
Datasheet, ICD, user manual, and application notes. If detailed documents require NDA, please mention the process.
We are currently performing a high-level trade study and would like suppliers to recommend suitable products or configurations, including any required external hardware such as RF switch, duplexer/diplexer, filters, power amplifier, or interface boards.
