PROCEDURE OF SURVEY
5 EXISTING FIRST ORDER CONTROL POINTS FROM CITY OF
ENCINITAS CONTROL ROS 18416 WERE OCCUPIED UTILIZING STATIC
G.P.S. RELATIVE POSITION TECHNIQUES IN COMPLIANCE WITH FGCC
STANDARDS AND SPECIFICATIONS FOR GROUP C FIRST ORDER
CONTROL AS DEFINED IN "GEOMETRIC GEODETIC ACCURACY
STANDARDS AND SPECIFICATIONS FOR USING GPS RELATIVE
POSITIONING TECHNIQUES VERSION 5.0, DATED MAY 11, 1988,
REPRINTED WITH CORRECTIONS AUGUST 1, 1989 ". TWO ASHTECH
Z -12 DUAL FREQUENCY RECEIVERS AND THREE ASHTECH Z
SURVEYOR DUAL FREQUENCY RECEIVERS WERE UTILIZED ON MARCH
14TH 2013 TO OCCUPY EACH STATION. 5 SECOND INTERVAL
SAMPLING RATE WAS USED WITH OCCUPATION TIMES VARYING
FROM 5 HOURS TO A MINIMUM OF 90 MINUTES. TIES FROM 4
CONTINUOUSLY OPERATING REFERENCE STATIONS (CORS) WERE
ALSO INCORPORATED INTO THE CONTROL NETWORK TO ESTABLISH
ONE NEW STATION.
COLLECTED DATA WAS PROCESSED USING SOKKIA SPECTRUM
SURVEY GPS POST PROCESSING SOFTWARE VERSION 4.0. CONTROL
MONUMENTS WERE FIXED TO PERFORM A LEAST SQUARES
P478 ADJUSTMENT SPECIFYING A DESIRED NETWORK ACCURACY OF
0.010m HORIZONTAL PLUS 10 PPM AT 95% CONFIDENCE LEVEL.
THE CHI SQUARE TEST ON THE VARIANCE FACTOR WAS 1.2792
INDICATING THE OBSERVA11ONS WERE WITHIN THE SPECIFIED
STANDARD DEVIATION.
THE NETWORK WAS CONSTRAINED IN TWO SEPARATE
ADJUSTMENTS, ONE FOR CALIFORNIA COORDINATE SYSTEM 1983,
1991.35 EPOCH AND THE SECOND FOR CALIFORNIA COORDINATE

UTILIZING DIFFERENTIAL LEVELING TECHNIQUES IN COMPLIANCE WITH
FGCC STANDARDS AND SPECIFICATIONS FOR THIRD ORDER
CONTROL AS DEFINED IN "STANDARDS AND SPECIFICATIONS FOR
GEODETIC CONTROL NETWORKS DATED SEPTEMBER 1984 ". A
TOPCON DL101 C ELECTRONIC LEVEL WITH FIBERGLASS STAFF WAS
USED TO RUN TWO DIRECTIONS FROM FIRST ORDER CONTROL
POINT NO. 1038 FROM CITY OF ENCINITAS CONTROL ROS 18416.
STATION 1038 WAS INCLUDED IN THE LEVELING FOR ROS 18416.
