About 20nm Northeast of DEN on the LAWGR arrival; 12;000 ft. we received a GPS-R fail; then a GPS-L fail. Confirmed failure on FMC NAV-STATUS page. Then we received the 'xnpndr fail' light on transponder. ATC still had us radar contact. Intercepted LOC on [Runway] 35R. Aircraft symbol showed left of course on NAV page; but right on with LOC/GS with Number 1 and 2 VHF as well as Standby. At about 10;000 ft. MSL we got a TERR POS indication momentarily on NAV display. We landed safely on [Runway] 35R; and during rollout and taxi onto P7; GPS and XPNDR came back on with normal ops.
Air carrier Captain reported loss of GPS and transponder on arrival into DEN. Both systems returned to normal after landing.
