  • Egil updated on MASSIVE status. 
    • Launch scheduled for 2019-2020
  • S-band frequency bands. 
    • Uplink: 2025-2110 MHz. 
    • Downlink: 2200-2290 MHz.
  • UHF
      • Frode has been investigated what they did in the past.
      • It's up to the administration if it's fine to file an application for amateur band.  Frode is a bit reluctant to do this because of interference and safety.
      • From 432-438
    • has
      • there's also the Earth Exploration Satellite Service. It says active so it's to uplink data from sensors in the ground. So that's why TTC shouldn't be here
    • necause
      • because you can ruin other low power EESS sensors
    • all around the world
      • .
      • So we should aim from 400.15-402. NKOM has filed another EO satellite in this band. It could also be 402-403 but there is more interference.
      • Power density or spectrum mask for this? Don't think so. You file the application stating power limits and so on
    • ,
      • . This is published so that other administrations will complain. You have to find a way to coexist.
      • Do we have to come up with a frequency? Yes, ITU will only publish it. We should file the entire band and then will narrow it down after comments from administrations.
      • Satellite operators send NKOM the files created by Spacecom. 
    • Book number2
      • Requested info for Spacecom. Book number 2 Appendices. Appendix 4
    • . Requested info for Spacecom
    • and
      • with a fax. In a few weeks it'll be published. NKOM will get comments from
    • adiministrations
      • administrations (this will last 3 months).
      • What's the timeline of getting there? You will never get here, but we can launch and as long as we don't harm anyone
    • else
      • it'll be fine. In the unlikely case that someone complains about it after it's launched, NKOM will tell us to turn the satellite off.
      • We don't know exactly the orbit we will be in. But we
    • write
      • just write an approximate one (best guess). Put
    • it
      • in something that is close to where we want to be.
      • Some experiments for communication to Arctic nodes. We could demonstrate to do this at these frequencies. Uplink sensor data to satellite, it's an active sensor on the ground. 401-402. Or we could file in 432-438.
         for the sensors.
      • Feeder link? Can we do 2-way link in 401-403 and 432-438? 401-403 just uplink. You have to comply
    • ti
      • with table 5 in frequency table so it'll say direction. 400.15-401 will be complicated but we
    • cnad o it in
      • can use it, or 402-403. Space operations would not include 2 way comm for sensors. NKOM assumes it's both directions in 432-438 as EESS, so it'd be to operate sensors both ways.
      • Can we use all the way from 432-438 for sensors? It depends on what interference we want to accept. NKOM will talk to their supplier to see if there are other satellites using spread spectrum.
      • NKOM suggests to talk to satellite supplier to see if we can operate in 401.
      • For ground station filing it's easier. We can take a look at previous filings
