You're right, according to the design:
Spy MkI class AM Sensor Sat 300 tons 24 Crew 55 BP TCS 6 TH 0 EM 0
1 km/s Armour 2-3 Shields 0-0 Sensors 1/1/0/0 Damage Control Rating 1 PPV 0
Annual Failure Rate: 0% IFR: 0% Maint Capacity 115 MSP Max Repair 22 MSP Est Time: 37.61 Years
AMM Sensor MR1-R1 (1) GPS 22 Range 1.1m km Resolution 1
My maintenance facilities are capable of maintaining ships up to 10000 tons, so that should not be a problem either.
However, the mainenance clock on my sattelites keeps ticking.
The mainenance clock for this particular sattelite is 14.46 years, even though it has been in overhaul since it had 7 years on it's clock.

This design is classed as a military vessel for maintenance purposes
Not the strange value for the sensor as well.
I guess this is yet another thread to link to the bug reports section for 5.2
I hope Steve takes my bug reports seriously, since I've posted so many in such short time
