OWL (On-board Whereabouts Locator) is a VHF transmitter capable of sending valuable data in the form of short messages over the VHF channel. This in-orbit automatic identification and localization system provides access to satellite position data, facilitating spacecraft localization and identification even before establishing a connection. 

• It features a platform-independent design.
• It can fit into the spacecraft’s Tuna Can without occupying payload space.
• It is equipped with its own battery, enabling independent operation from the platform for a minimum of 18 hours.
• It includes a secondary communication subsystem that can provide ancillary data during the commissioning phase.
• It offers easy plug-and-play integration.
• It can gather additional health and telemetry data if it has access to additional power sources from the satellite
