Research RF COTS options
IQSpaceCom
- Question: EM vs FM?
- @Liam: Electromag/frequency modulation?
- Googling…
- “Model in quantity”
- @Reid Sox-Harris: Might have something to do with manufacturing, may need to select the quantity of each one.
- @Liam : They might have two versions of the transciever, one FM, one EM.
- @Reid Sox-Harris : Don’t think it means frequency modulation
- Will leave for later
- Require standard voltage range.
- @Reid Sox-Harris CCSDS is a space packet protocol. We need to pick which one we want
- Will go with the default just for the quote.
- Going with SPI.
- Frequency?
- @Reid Sox-Harris : N/A, we don’t have freq allocation yet
- The module has two TX channels
- @Reid Sox-Harris We want 1024kb/s for tx, don’t know if we have an uplink budget. Can pick arbitrarily, shouldn’t matter.
- @Liam : Should we go with the same for rx?
- @Reid Sox-Harris : No, we won’t be uploading much, should go 4K
- Don’t need any of the additional options
- @Reid Sox-Harris : EM might be engineering model, used for validation?
- @Abeer : Will email them back
Skylab
- Wants EM vs FM
- @Reid Sox-Harris : We want one unit.
- Target market seems to be for constellations.
- @Abeer : Want the nanolink phase 2 variant?
- @Reid Sox-Harris We just want the base model
- No need for a call with them yet.
- About 37K for a trasciever
- @Reid Sox-Harris: This is why we are also checking out IQSpaceCom
- @Abeer : Patch antenna is 16.5K, a ripoff
- When asked for clarification on TRL, some of the tests had a 9 or 7
