XR3 GPS Track Channel
Microchip. Made for XR3 & XR4 GPS receivers. Features XR3 GPS single track channel correlator and tracker. Also provides the glue logic to the separate MC68000 CPU(s) which performed the satellite tracking maths.
The large XR3 military black box had 5 of these chips to tracking one satellite each.
The XR4 Marine Navigator and XR4-PC had 2 of these chips, which multiplexed up to 4 satellites in each.
The cost reduced XR4-Light only had one of these chips and could multiplex up to 5 GPS satellite. Silicon wafer technology: 1.5 micrometre.
