SYSTEM DESCRIPTION AND INSTALLATION MANUAL 3 T CAS/Part No.9005000 (b) Mode Select Air traffic density has significantly increased since the inception of ATCRBS. Aircraft within the same approximate range and azimuth from the interrogator may interfere with each other’s replies. Much verbal communication is also needed to coordinate ATC, causing more traffic on communication channels. This also places a heavier burden on the air traffic controllers.
SYSTEM DESCRIPTION AND INSTALLATION MANUAL 3 T CAS/Part No.9005000 2 Air to Air Communication Traffic Alert and Collision Avoidance System and Mode S Transponders are an integral part of the Traffic Alert and Collision Avoidance System (TCAS).

SYSTEM DESCRIPTION AND INSTALLATION MANUAL 3 T CAS/Part No.9005000 an ATCRBS interrogator (no P4), the Mode S Transponder responds with a standard ATCRBS reply. An uplink interrogation pulse group, which includes a P4 pulse, makes the Mode S Transponder prepare to measure the P4 pulse width. As soon as the Mode S Transponder detects the rising edge of the P4 pulse, it disables its ATCRBS reply. It then looks for a pulse width of 0.8 or 1.6 microseconds. A pulse width of 0.
SYSTEM DESCRIPTION AND INSTALLATION MANUAL 3 T CAS/Part No.9005000 Inside the P6 pulse, the first phase change occurs 1.25 microseconds into the pulse. This phase change is called the Sync Phase Reversal (SPR), and it is used to synchronize the transponder with the ground station. The SPR is used as the timing reference for the Mode S reply for uplink messages. Response time is 128 ±0.25 microseconds.
SYSTEM DESCRIPTION AND INSTALLATION MANUAL 3 T CAS/Part No.9005000 There are two fundamental differences between the uplink message and the downlink message, as follows: ● The uplink burst is at 4 megabits per second, while the downlink is at 1 megabit per second. ● The uplink uses DPSK, while the downlink uses Pulse Position Modulation (PPM). Using PPM, there is one pulse for every bit, either in the first half or the second half of the bit interval (window).
