Due to GPS jamming operations at SLC our aircraft is severely affected. We were given the SEVYR2 departure which is 260 heading on departure RV on course. Looking at the schematics of the departure both pilot flying and I had interpreted 260 heading to intercept 193 radial off of TCH on course. We began to intercept the radial and ATC noticed us turning and corrected our course back to the departure heading. A fix would be to thoroughly read the textual description and not rely on the picture diagram.
Embraer Phenom 100 First Officer reported losing a reliable GPS signal; which he attributed to military activity in the area. This resulted in a deviation from the published departure which was remedied with ATC assistance.
