Dear smallsat / nanosatellite / CubeSat developers,

as you may be aware, obtaining frequency spectrum for nanosatellites is not always easy. Especially, experimental / technology proof-of-concept demonstration missions find it increasingly more difficult to find spectrum in todays crowded bands. Whilst for some missions, amateur radio spectrum might fit the bill, for others this is less suitable since the mission does not fully meet the criteria in order to operate in the bands allocated to the amateur satellite service. On the other hand, "commercial" or research space allocations often are not feasible from a budget point of view because of the large fees involved, and the associated long coordination times may far exceed the time to design, develop and build a small / nanosatellite.

Through experience from our customers, and also through our own, ISIS has identified this problem as a potential long term showstopper for the emerging nanosatellite market. We will attend the World Radio Conference later this month as part of the Dutch national delegation. Although nanosatellite spectrum is not on the agenda of this WRC, we plan to make use of the opportunity to informally sound the various opinions on this matter and investigate potential possibilities for creating a future proof solution ensuring the spectral needs of the community are met. This is potentially in line with discussions already going on in for example ITU study group WP7B.

If you have any input on this matter, we would love to hear from you so we can take this into account during our informal discussions with the various attendants at the WRC.

Also, if you are present at the WRC yourself, this might be an excellent opportunity to discuss the topic in person. We might be able to share some preliminary observations during our presentation at the European CubeSat Workshop in Brussels later this month.

kind regards,

Wouter Jan Ubbels
