: Alignment with international Radio Regulations to ensure cross-border coordination and compliance.

While Prösch's handbook serves as a practical guide for signal identification, it operates alongside official standards from organizations like the International Telecommunication Union (ITU) ITU-R Handbooks : Official documentation such as the ITU-R Handbook on Satellite Communications Handbook on Spectrum Monitoring

The handbook, specifically the 2019 edition, is a 442-page technical manual focused on the identification of unknown satellite signals received in the modern radio spectrum. It is widely used for spectrum management to maximize efficiency and minimize interference. Core Technical Content The handbook and its associated files typically cover:

: Detailed descriptions of digital waveforms such as FSK (Frequency Shift Keying), PSK (Phase Shift Keying), and DSSS (Direct Sequence Spread Spectrum).
