Mk45 current ballistic ammo has a current max range of 13nm / ~24km, BAE Inc looked at various alternatives but went with the Vulcano as had the longest max range of ~90km / 48 nm, though comes at expense of lower payload. Vulcano uses GPS guidance so can be easily jammed/spoofed, looking at infra red.
Video has a clip of part of the Mk45 automated magazine in operation, T26 so far only buyer, presumably will be fitted to Hunter and CSC.
(BAE Inc licensed the Italian Leonardo Vulcano round in 2017 for use in AGS, following the USN cancellation of the LM LRLAP rocket round due to cost 'rocketing' to $1M per round for use in the Zumwalt BAE Inc AGS 155mm main gun, but USN looked at alternatives including Vulcano and decided not to make AGS operational).

"easily spoofed" seems to be your words. IR & SAL is being looked at for moving targets, nothing to do with GPS.
Google, you can find numerous, hundreds of articles on ease with you can jam or spoof GPS.
Jamming GPS

It appears even ISIS can jam GPS ‘We’re down to the last few villages’: British air campaign in Syria faces new phase By: Sebastian Sprenger August 25, 2018 "There is also occasional GPS jamming, said one weapons engineer, who, like most officials briefing reporters, spoke on condition of anonymity due to personal security. It happens irregularly — sometimes twice per day, sometimes with days in between — affecting the satellite-guided targeting of the Paveway bombs. When jammed, the pilots have the option to switch to the bombs' laser-guidance mechanism."

Spoofing GPS
BBC Study maps 'extensive Russian GPS spoofing' 2 April 2019
"Russian President Vladimir Putin has a bubble of spoofed GPS signals projected around him when he visits sensitive locations, a study suggests.
It involves the state using strong radio signals to drown out reliable navigation data, says non-profit C4ADS.
The report by the think tank documents almost 10,000 separate GPS spoofing incidents conducted by Russia.
Most incidents affected ships, said C4ADS, but spoofing was also seen around airports and other locations.

Norway at odds with Russia over GPS jamming, Mar 19, 2019
"Norway says it has electronic proof that Russian forces disrupted GPS signals during recent NATO exercises, and has demanded an explanation from its eastern neighbour, the Nordic country’s defence minister said on Monday (18 March)."

In response USAF has launched 2 of 10 of their new 3,880kg LM GPS III satellites which provide three times the accuracy and eight times current anti-jamming capabilities compared to current satellites, to be followed by 22 upgraded IIIFs, programme to be completed by 2034. The GPS Raytheon Next Generation Operational Control System (OCX), needed to enable the full range of the new GPS III capabilities is running four years late and over budget. The shortcoming is that in a great peer war GPS satellites would be among the first to be targeted by anti-satellite systems.
USN reinstated navigational training in 2016 with sextants, quantum positioning system in R&D as one possible GPS replacement.
That's why would expect the Vulcano using GPS round to be non-effective as Paveway in Syria when jammed, will be of interest to see when the new gen GPS III satellites come on line if a new gen jammers are as effective as the current ones, perhaps one of the reasons why USN did not pick Vulcano for the Zumwalt AGS 155mm gun.
Do not expect RN to fund Vulcano for T26 for similar reasons, with Mk45 5" using the US ballistic 70 lb shell limited to 13nm max range for NGFS, a longer range shell would be advantageous.
