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 […]
