Reliable communications over long distances between control centers of airports and aircrafts.

“SAIT” is a “Securitas Solution” to airport authorities of very high quality and reliable aeronautical communications over long distances with aircrafts.

Long Range HF Communication Solutions

HF communication (3 MHz to 30MHz) provides cost-effective, non-line-of-sight communications, secure means of communications, reaching far beyond the radio communication range of VHF radio waves.

In aviation, HF radio equipment is covering voice communication to international airports and long distance aircraft communications. HF transmissions are also useful where satellite use is neither possible nor practical, such as at the North and South Poles regions or when too expensive.

5 kW ground-to-air HF transmitters for Santa Maria Airport (Azores)

Based on well proven technology of the HF technologies, HF systems play a vital role in providing means of contact in difficult circumstances. Use of new computer technologies and other hardware solutions strongly reduce HF transmissions fluctuations (due to propagation vagaries and atmospheric radio noise) and provide privacy through scrambling.

HF Transmitters from 1 kW PEP (CST3001) up to 5 kW PEP (CST3005) are used by SAIT for these ground-to-air communications.
