STL is LEO PNT

STL is a strong, continuous LEO PNT signal that provides timing synchronization services to 5G networks everywhere—including urban and rural locations.

You can use STL technology as a standalone timing synchronization service or as a backup to GPS/GNSS. Simply place your STL and GPS receivers next to each other in RAN equipment. If you lose your GPS signal, your timing will seamlessly fail over to STL. You can also make STL your primary timing source and use GPS for backup.

STL signals are 1000X stronger than GPS and GNSS signals—making them difficult to jam and manipulate. The STL technology uses complex beam patterns from LEO satellites and cryptographic security to provide your network with multiple layers of protection.

STL offers the advantage of utilizing a small indoor antenna to deliver timing signals that penetrate most structures, including buildings with low-emissivity (Low-E) windows or metal and concrete siding and roofing. This means that in-building wireless installations that leverage STL can maintain synchronous timing without the need for an outdoor GNSS antenna.

STL antennas can also be installed outdoors similar to GPS/GNSS antennas.

Satelles partners with solution providers and original equipment manufacturers (OEMs) that engineer user equipment (UE) incorporating STL technology. You can bundle STL technology with other equipment or purchase it separately. Either way, STL is far less expensive than many alternatives to GPS timing synchronization, such as time over fiber or beacons.
