SanoSat-1 has received a frequency licence for 436.235 MHz. SanoSat-1 is the first satellite made in Nepal. SanoSat-1 is planning to launch into a 400-500km orbit in Q4 2020 as part of the Alba Orbital Cluster-3 launch. The responsible person for this licence has been made to Mr. Felix Paez from AMSAT-EA since the licencing […]

Frequency Co-ordination with ITU
Every Satellite must be coordinated with ITU (International Telecommunication Union) for the frequency usage. This is done in order to avoid Interference: Frequency Allocation, Frequency Coordination, Power Limit, Recording and Monitoring. It must be done only through the National Regulatory Body responsible for ITU coordination. According to ITU, the responsible body for Nepal is: MoCIT […]
