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're looking for a complete 3p PocketQube platform — structure, OBC, EPS, and UHF comms — compatible with the Alba Orbital AlbaPod deployer.
The satellite is a fixed payload with no moving parts and no camera — it carries visual markers on its exterior panels for testing proximity/detection sensors, plus a small onboard circuit that measures solar cell performance and sends data down over radio.
We need to deliver the finished satellite to our launch provider within 3 to 5 months, so lead time is critical for us.
To save time on both sides, please include everything in your first response — quotation, lead time, flight heritage, ICD, CAD model, and datasheet — rather than a partial reply, so we can evaluate your offer in one pass without needing follow-up requests. Also let us know if staged or deposit payment is available, as we're an early-stage company working with a limited budget right now.

We require an S-band transceiver for our 3U CubeSat project, operating in the 2025–2100 MHz receive (uplink) band and the 2200–2290 MHz transmit (downlink) band. The transceiver should support a minimum data rate of 4 Mbps and provide a minimum transmit output power of 30 dBm. The module should preferably be compatible with the PC/104 mounting hole standard for ease of integration into our spacecraft.
In addition, we are looking to procure a deployable UHF antenna operating in the 401–402 MHz frequency range. The antenna should be mountable on a 1U CubeSat face and be rated to support a 30 dBm transmit output power.
Our current avionics architecture uses SMA connectors for RF interfaces and Harwin Gecko and Molex Pico-Lock connectors for board-level interfacing. We also use RS-485, USB, and Ethernet as our primary communication interfaces. While compatibility with these connectors and interfaces would be preferred to simplify system integration, it is not a strict requirement.
Please let us know if you require any additional technical or mission-specific information to assess the suitability of your solution for our application.
We are developing an Electrical Power System (EPS) for a CubeSat and are looking for qualified suppliers to provide Battery Management System (BMS) hardware or related solutions. The requested system should support a 4-series (4S) lithium-ion battery configuration suitable for CubeSat applications, including battery protection, cell balancing, voltage and current monitoring, temperature monitoring, state-of-charge estimation, and fault detection. The solution should be compatible with spacecraft power systems and operate reliably in low-power, high-reliability environments. We request detailed datasheets, CAD models, user manuals, lead time, quotation, and any available flight heritage information. If available, please include interface documentation (ICD), electrical specifications, reference designs, and integration guidelines for CubeSat EPS applications.

| ENVIRONMENTAL & RELIABILITY | ||||
| Operating Temperature Range (°C) | -40°C to +80°C (standard LEO) | Minimum operational capability: -24°C to +61°C | Preliminary mission acceptance envelope; final range must also cover spacecraft thermal-model MPT values. | |
| Survival Temperature Range (°C) | -50°C to +90°C | Preferred design qualification capability: at least -34°C to +71°C | Corresponds to current SpaceX qualification margin around the minimum acceptance range. | |
| Thermal Vacuum (TVAC) Tested? | Minimum 4 cycles required at limits | Protoflight baseline: -29°C to +66°C, 20 cycles total; at least 4 TVAC cycles preferred | Supplier to provide standard component qualification/acceptance profile and identify any delta to mission requirements. | |
| Radiation Tolerance (TID, krad) | > 20 krad (Si) for standard LEO | No active-electronics TID requirement; all insulation, adhesives and materials must suit 5-year LEO plus EOL operations | Provide radiation/material suitability evidence and any life-limiting degradation mechanisms. | |
| Random Vibration (grms) | NASA GEVS (14.1 grms) compliance | Protoflight: SpaceX MPE +3 dB ≈ 7.88 gRMS, 1 min/axis, 3 axes | Prefer existing design qualification evidence at MPE +6 dB ≈ 11.14 gRMS, 2 min/axis, 3 axes. | |
| Shock Tolerance (g) | > 1000g SRS at 1000Hz | Protoflight advised: MPE +3 dB, Q=10; ~42 g @100 Hz and ~1,414 g @1,000-10,000 Hz; 2/axis | Prefer design qualification evidence at MPE +6 dB: ~60 g @100 Hz and ~2,000 g @1,000-10,000 Hz; 3/axis. | |
