- 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.

- NKOM will look into the TIES account. Maybe they can pay for it.
- Spacecom files with frequencies will be sent to NKOM. NKOM will check it and send it to ITU
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
- ACTION LIST
- NKOM investigate ITU fee NKOM send

- Filing fees. NKOM usually invoices customers but will look into how much it'll be.
