Abstract: System, devices, and methods for facilitating time synchronization of gateway devices are disclosed. A relay device can generate, via a Global Navigation Satellite System (GNSS) component, a plurality of pulse per second (PPS) signals based on establishing a connection with at least one GNSS satellite. The plurality of PPS signals are time synchronized with a GNSS clock. The relay device can determine a first PPS signal of the plurality of PPS signals associated with the at least one gateway device sending a beacon to at least one end device. Based on the determined first PPS signal, the relay device can determine a second PPS signal of the plurality of PPS signals associated with sending a message to the at least one gateway device. The relay device can send the message to the at least one gateway device based on detecting an edge of the second PPS signal.

Abstract: A surveying pole system comprising a surveying pole including two telescopic sections for providing length adjustability. At a first end of the surveying pole, a pointing tip is disposed for positioning on a target point of the environment. At a second end, a length reference point is disposed. The surveying pole also includes a locking mechanism for locking the length adjustability in respective lock-in positions. Each of the lock-in positions provides a corresponding distance between the pointing tip and the length reference point. A plurality of coded identifiers have a predetermined code associated with one of the lock-in positions. The surveying pole also includes a coded-identifier reader for reading the code of a respective coded identifier associated with the respective lock-in position, a communication device configured for transmitting a signal to a surveying instrument, wherein the signal is based at least on the read code.

Abstract: The present invention provides a low-cost and low-volume mode A/C/S transponder positioning system to detect the position of a target aircraft, or intruder, outside the range of a secondary surveillance radar system. The system uses a signal of the intruder to pinpoint the location of the intruder. The system can be used on both the ground and on an aircraft in a full 360 degree range around the system.
