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: A wireless apparatus mountable to a vehicle includes a transmission function unit, a detector, an acquirer, and a controller. The detector detects a startup of the vehicle. The acquirer acquires start position information of the vehicle at a start timing at which the detector detects the startup of the vehicle. The controller examines whether a start position indicated by the start position information is within a designated region, and determines whether to activate the transmission function unit based on the examination result. Alternatively, the detector detects an operation end of the vehicle, and a startup subsequent to the operation end. The acquirer acquires position information of the vehicle at timings of detecting the operation end and the startup of the vehicle. The controller discriminates whether the distance between the positions indicated by the two pieces of the position information is greater than a threshold, and determines whether to activate the transmission function unit based on the discrimination result.

Abstract: A method and control system for optimizing active measurements are presented. In an embodiment, the method includes emitting at least one active signal in at least one direction; determining whether a return signal is detected for each of the at least one active signal; upon detecting at least one return signal for the at least one active signal: measuring a strength of each return signal; comparing the measured strength of each return signal to at least one optimal return signal strength; and determining, based on the comparison, an optimized configuration for active measurement emissions in one or more directions.

Abstract: The invention relates to an apparatus and method for augmenting the 3 dimensional position information obtained from the NAVSTAR satellite-based global positioning system (“GPS”) system. Such systems can be impacted by physical obstacles that prevent the receipt of the satellite signals or as a result of sun spot activity that introduces noise into the signals thus causing them to become intermittently unavailable and/or making them less accurate in the course of normal operation. Therefore, an improved positioning solution that can operate under such poor GPS operational conditions is needed. The apparatus and method of the invention augments GPS with dead reckoning techniques when GPS signals are unavailable or inaccurate. The apparatus and method of the invention demonstrates highest value when applied to blasthole drill positioning applications in open-pit mines.

Abstract: An Automatic Dependent Surveillance-Broadcast (ADS-B) system, and method of harmonizing a transponder Squawk code and an ADS-B system, ensures that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code. The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft, and the transmitted transponder Squawk code is received by a device positioned onboard the aircraft in which the transponder is installed. The ADS-B system is updated with the received transmitter squawk code. The squawk code is transmitted using the ADS-B system.

Abstract: An improved aviation transponder is discussed herein. The improved aviation transponder demonstrates improved cohabitation and survivability characteristics, allowing the transponder to be placed near other antennas without causing or receiving interference, and reducing potential damage caused by high-energy electromagnetic fields, such as those experienced near an air traffic control (ATC) or military radar installation. Additionally, a small form factor of the transponder results in a smaller, more compact aircraft that consumes less energy, reduces heat dissipation, and maximizes battery life and/or flight time. The transponder may comply with modular interface standards, and may include a radio configured for transmitting 200-watt signals. Based at least in part on the improved performance, the transponder can be implemented in unmanned aerial vehicles (UAVs), for example.

Abstract: A system for verifying an aircraft instrumentation value comprising: an Air Data Test Module (ADTM) configured to pneumatically simulate at least one instrumentation value based upon a pressure set-point. The pneumatically simulated instrumentation value corresponds to the pressure set point and is reported by an aircraft transponder. A receiver module receives the pneumatically simulated instrumentation value transmitted by the aircraft transponder. A signal processor, is operative to (i) control the ADTM, (ii) command a prescribed instrumentation value to be simulated by the ADTM, (iii) compare the prescribed instrumentation value to the pneumatically simulated instrumentation value, and (iv) issue a pass signal when the values match, and a fail signal when the values differ by a threshold value.

Abstract: A ground-based source of a jamming signal capable of disrupting a GNSS satellite-based navigation system, for example a GPS jammer, is located with a detector carried by a suitable platform, for example an airborne UAV or missile. The detector, when the platform is at a first location, measures a characteristic of the jamming signal. The platform and its detector are then moved to a chosen second location, from which a further measurement of the jamming signal is made. The measurements made by the detector are then used to determine the location of the source of the jamming signal.
