摘要： A method and apparatus for encoding and decoding data on navigation signal pulse pairs utilizes pulse position modulation (PPM). The pulse interval between a first pulse and a second pulse of the pulse pair is varied depending on whether the logic value of the data to be encoded is a logic "0" or a logic "1". A tri-graph encoding process converts the raw input data into encoded input data. Each input data bit is encoded into three bits with each bit having the same logical value as the input data bit. The encoded input data is then encoded on the navigation signal using a pulse position modulation (PPM) technique. A decoder recovers the encoded data and provides an error correction process for high data integrity that corrects certain bit errors that may occur during the transmission and reception of the data on the navigation signal. The error correction process detects and corrects errors such as a missing bit, an extra bit or a bit error.

摘要： In a two way ranging system of the type employing pseudonoise spread spectrum codes there is provided a method for correcting the navigational system of one of two moving stations in space to compensate for relative drift. The point positions of the two stations are calculated by the on-board navigation systems of the individual stations at a first and subsequently at a second position after relative movement. The range from station 1 to station 2 is calculated employing the highly accurate pseudonoise communications ranging systems. The range uncertainty of the range calculation and the trigonmetric relation of the two calculated ranges and the include angle between the line of sight of the range directions is employed to calculate a range of uncertainty parallelogram more accurate that the navigation systems. When a station's point position is indicated by its navigation system to be outside the parallelogram, the navigation system is corrected to compensate for relative drift.

摘要： An RF pulse transmitter, for use in precision distance measuring equipment (DME/P) of a microwave landing system, includes appropriate circuitry to correct for incidental phase modulation (IPM). The pulse transmitter includes a modulation circuit for generating an RF pulse having a pulse peak. A reference phase control circuit is provided to generate a reference signal. A phase detector receives the RF pulse and the reference signal and in response thereto generates a phase error signal. The reference phase control circuit includes appropriate circuitry for adjusting the phase of the reference signal applied to the phase detector to thereby drive the phase error signal to a predetermined value at the pulse peak. A pre-distortion circuit generates a pre-modeled correction signal pulse for use in correcting for incidental phase modulation (IPM). A phase correction control circuit receives the phase error signal and in response thereto modulates the phase of the carrier signal to correct for the incidental phase modulation.

摘要： This invention discloses a DME which employes an improved technique for validating received replies. The technique employed reduces lock-on time by analyzing all of the range data received within a set time period following the transmission of an interrogation pulse pair rather than just one range figure for each interrogation cycle. The DME also provides improved accuracy and reliability by varying the width of the range gate used in analyzing the received range data in accordance with the time difference between the two interrogation cycles from which range data is being compared with system status, i.e., whether the system is in the locked position or not.

摘要： A range processor for airborne distance measuring equipment in which coherency of reply signals from the ground based DME station is determined by incrementing the contents of storage locations of a random access memory device for each reply signal according to the time of reception of the reply signal and for decrementing the contents of the storage location if no reply signal is received. Whenever the contents of a storage location exceeds a threshold value a range gate is generated so that the next reply received within the range gate causes the time of reception of the reply to be stored as range data.

摘要： This DME ground station permits the distance from the touchdown point (where no transponder can be installed) to be measured on the aircraft without any change in the airborne equipment. The time difference between the reception of an interrogating signal and the transmission of a reply signal is chosen so that the transmission of reply signals from the DME transponder located on one side of the runway corresponds to a transmission from the touchdown point with respect to the signal transit time.On the ground, a DME transponder is located on one side of the runway on a level with the touchdown point, and a receiver and a direction finder are provided on the other side.

摘要： A ranging timer allows decoded data pulses to toggle a flip flop, thereby initiating a transmission cycle. In a specific embodiment, the data pulses condition a second flip flop to energize the DME transceiver. During the next negative excursion of a 96 microsecond reference clock, the second flip flop is toggled, and during the next period of the reference clock, the decoder is disabled, the transmitter-modulator is energized, the ranging timer is enabled, and the first flip flop is reset. Since the time between the decoded data pulses is variable, jitter is built into the commencement of each transmission cycle.
