2.5 Memory
The GSR2700 IS comes standard with 64 MB of internal memory
to support post-processing applications. For information about
how many hours of data can be stored in memory, see Section 6.5,
Data Storage Capacity , page 54.
NOTE To determine the memory capacity of your receiver, use
Spectrum Survey or SDR+ . If the internal memory needs to be
serviced or upgraded, see your local Sokkia distributor.
2.6 GPS Antenna
The GSR2700 IS features an integrated GPS antenna (L1/L2) with
Pinwheel™ technology. This patented antenna provides
exceptional multipath rejection and performance equivalent to a
typical choke ring antenna.

There is one tape measure anchor point on the circumference of
the receiver from which the antenna height can be measured.
This height measurement location enables the use of a Sokkia
tape measure (custom tape with offset scale and reference tip) or
a typical hardware store tape measure.
A phase center offset label is located on the underside of the
receiver (see Figure 6,
Mounting Socket and Phase Center Offset
Label , page 11 for details).
