CMR
C
ompact M easurement R ecord. This is an RTK
correction protocol.
EDGE
E
nhanced D ata rates for G SM E volution. The EDGE
protocol allows improved data transmission rates, as
an extension of standard GSM. EDGE is a third-gener-

H
igh- S peed D ownlink P acket A ccess. HSDPA is a
protocol for cell phone data transmission. It is
referred to as a 3.5G technology (G stands for Gener-
ation). The HSDPA protocol provides download
speeds on a cell phone that are equivalent to ADSL
(Asymmetric Digital Subscriber Line) downloads on a
landline. HSDPA evolved from, and is an improvement
on, the W-CDMA protocol (a 3G protocol).
Latitude
The angle between the ellipsoidal normal and the
equatorial plane. Latitude is zero on the equator and
90° at the poles.
Longitude
Longitude is the angle between the meridian ellipse
which passes through Greenwich and the meridian
ellipse containing the point in question. Thus, longi-
tude is 0° at Greenwich and is measured either east-
ward through 360° or eastward 180° and westward
180°.
