Considering they're matching all the stuff to fiscal years, I'd say this 
sounds more like a call to improve/preserve their budget situation in the 
current economic climate, rather than a technical issue. 

Glonass doesn't really come into the story as the article is not about LOSS of 
gps capability, just precision/lock time degradation. There are methods of 
improving this anyway by making more sensitive/accurate 
equipment/calculations. GPS became ubiquitous as you could get a reasonable 
reasonable quality fix with dirt cheap components. Adding a GLONASS into the 
mix would drastically increase cost, so unless you already have a need for 
civilian very high precision positioning (or you live really high up North as 
some of our Scandinavian friends :), I couldn't really justify it. AFAIK 
Galileo (if it was anywhere near operational) would be a better match as the 
tech aspect is more similar to GPS so it could be easily adapted for 
dual-receiving purpose. Maybe this announcement will give the project a 
little boost :)
