Gatehouse Satcom provides market-leading communications software to the global satcom industry. During the last 25 years, we have developed more than 15 different software solutions enabling  connectivity from space. Currently, we are developing the bi-directional 5G NB-IoT NTN software (the NodeB), which will be compliant to the 3GPP standard. It can be used in satellite systems for GSO / MEO / LEO satellites, user terminals, and ground infrastructure, supporting up- and downlink. In 2023, we started development on the PHY layer for at 5G NR (New Radio) NTN NodeB. With our Prove & Deploy approach we serve clients with studies, demonstrations and software for deployment.
