As reported by FierceWireless: Some Washington security officials have voiced concerns over a plan
to use Russia's satellite location system to augment an effort in the
United States to improve U.S. wireless carriers' ability to find 911
callers. In response, U.S. wireless industry executives and others have
argued that using Russia's GLONASS location system won't create security
problems for Americans.
The debate stems from a November announcement among Tier 1 U.S.
wireless operators and the Association of Public-Safety Communications
Officials and the National Emergency Number Association to improve carriers' ability to locate 911 callers, including those indoors.
The
proposed solution from the carriers and APCO and NENA will use Wi-Fi,
Bluetooth and other technologies supplement location data obtained
directly from phones' GPS chips. One of the other technologies that
could help improve location accuracy is Russia's GLONASS location
system, which uses satellites and operates much like the United States'
GPS system.
According to multiple reports, it's the reliance on technology from
Russia--which has a rocky political relationship with the United
States--that has caused some concerns. James Clapper, director of U.S.
national intelligence, wrote in a letter to Defense Secretary Chuck
Hagel that Russian President Vladimir Putin might use GLONASS "as a
weapon" against the United States, potentially holding the 911 system
"hostage."
But NENA and others blasted that argument.
"The consensus plan discusses the GLONASS system as a new component of handset A-GNSS capabilities because it is the only globally-available
GNSS (Assisted Global Navigation Satellite Systems), other than
NavStar/GPS that is currently operating," NENA wrote in a statement.
"The consensus plan does not restrict carriers' ability to add or
substitute other GNSSs, such as the European Galileo and Chinese BeiDou
constellations, as those systems come online over the next 5-7 years.
However, neither of these systems is currently available."
Added NENA: "Because handset A-GNSS chips can operate with any
combination of satellites from any supported constellation, adding
GLONASS support to existing GPS capabilities will not provide the
Russian Federation with any leverage over U.S. E9‑1‑1
capabilities: Even if the GLONASS system were shut-down completely,
handsets in locations with clear views of the sky could still calculate
location estimates based solely on measurements of U.S. GPS satellite signals."
When they announced the proposed solution in November, Verizon Wireless, AT&T Mobility, Sprint and T-Mobile US said
they hope to use it to obtain a location fix using heightened location
accuracy technologies for 40 percent of all wireless 911 calls within in
two years; 50 percent within three years; 75 percent within five years
and 80 percent within six years. Those goals generally line up against
milestones discussed by the FCC, which has been investigating ways to
improve the technologies used to locate 911 callers. The FCC has said
more accurate location technologies could save 10,000 lives every
year--locating 911 callers who are in a building is particularly
critical for emergency responders who might have to search dozens of
floors for callers in skyscrapers.
