SPEAR location
Longitude 78° 09' 15" N - Latitude 16° 03' 17" E - Altitude 458m (WGS84)
Decimal values: Logitude 78.154° N - Latitude 16.055° E - Altitude 458m (WGS84)
SPEAR array orientation
Array north direction (perpendicular to the long dimension) is 14 degrees west of magnetic north.
Declination at the site is approx 4 degrees east (2004 epoch). Angle between array north and true north is 10 degrees.
Inclination is 82 degrees (2004 epoch) i.e. 8 degrees off zenith.

Note that this assumes that the slope of the array has been compensated for in the beam forming calculations in the radar control software. For information the array slope is approx 4.7 degrees (down to the North) in the short dimension and 1.0 degrees in the longer dimension (down being to the East).
