Note that the headline on the article refers to a "rare orbit", and
refers to the orbit as geosynchronous but not geostationary.  With the
inclination (~63.8 degrees) of the orbit this satellite and its
predecessor (EKS-1, or Kosmos 2510) are in, a geosynchronous orbit (i.e.
having a period of 23hr 56min) IS known as a Tundra orbit, as the
article states, and one of the names used for these early warning
satellites is Tundra, so it may be that this was the original plan for
their orbit, but nearly two years after the launch of the first, it
remains in the familiar Molniya-type orbit with a period of half the
period of a Tundra orbit, and this is also the orbit this latest
satellite is in.
