Introduction
1. Historically, the development of geodetic infrastructure in
Indonesia was predominantly for surveying and mapping.
Since 1990, GPS technology has been used for survey and
mapping activities in Indonesia, especially horizontal
control networks (1st, 2nd, 3rd and 4th orders). GPS CORS
has been growing in Indonesia.
2. Stake holders who have managed more than 200 GPS
CORS are Geospatial Information Agency, the National
Land Agency (BPN), several national universities i.e. ITB,
UGM, UNDIP and ITS, and a few private sectors.
Introduction (Cont.)
3. Jaringan Referensi Satelit Pertanahan (JRSP) is a
reference stations network system which works
continuously for 24 hours nonstop (active station)
as CORS.
It can also be applied to dynamic cadastre,
geodetic framework that is as dynamic and has a
homogeneous accuracy.

Description of Control Centre
This software is used for :
a).Managing a wide range of devices to work
according to its function;
b).Regulating and monitoring the activities of
reference stations;
c).Controlling activity in the reference station
network;
d).Monitoring conditions recording of satellite data
received by each reference station;
e). Managing data and make corrections to
the rover position coordinates,
f). Regulating data transmission over the
Internet, and
g). Other functions related to the calculation
or the calculation of the position
coordinates and differentiation of data
presentation.
Description of Control Centre (cont.)
Two types of data communication :
1. Via terrestrial infrastructure
2. Via satellites.
Terrestrial data communication uses the media as a wired
and wireless access (direct data connections, frame relay,
VPN Multi-Service, and communication connection data
packets).
Connection between the reference station to the server or
to a control center is used via several types of data
communication.
Description of Control Centre (cont.)
At National land agency, the data is sent to the
server or the control center for encapsulation
encrypted (wrapped) and as if passed at a virtual
tunnel or tunnels (virtual tunnel).
With the method of Virtual Private Network (VPN),
then the safety and quality of the data flow from
the reference station to a central server to be more
secure (Idrus, 2009).
VSAT-IP works with IP based method.

transmitted to the satellite (satellite as a repeater) to
reach large areas or isolated areas. Examples of this
technology is VSAT (Very Small Aperture Terminal)
which is a station for data communication that serves as
a transmitter / sender and receiver data signals via
satellite. VSAT is a data communication based on TCP /
IP

Geodetic Services
Law No.11/ 4 of 2011 on Geospatial Information (Undang
Undang Informasi geospasial,
UUIG) is the first
legislation governing the implementation of Geospatial
Information in Indonesia.
UUIG also encourages the use of a single reference
(single reference) in the implementation of the Geospatial
Information Base (IGD).
Geodetic Services (Cont.)
National Geospatial Reference System (SRGN) is a 4dimensional reference system (includes a 3-dimensional
position and epoch) which is used as a reference in all
activities related to geospatial information, such as
mapping, cadastral, precision navigation, engineering
work, as well as studies geoscience, geodinamic and
other.
Geodetic Services (Cont.)
The National Geospatial Reference System (SRGN) is a system
and national infrastructure, data, software, and knowledge that
evolve continuously.
The SRGN in Indonesia is managed and maintained by the
Geospatial Information Agency (BIG). The SRGN is a foundation
for all positioning activities, the collection, and spatial data
management.
Geodetic Services (Cont.)
JRSP will be one of national potential networks to define
SRGN. In the application of this new SRGN, datum is a
datum defined semi-dynamic conditions that facilitate the
movement of the earth's crust.
Thus this datum will be updated periodically.
Basically SRGN function is as a national reference for
mapping the coordinates of a mapping activity.
Geodetic Services (Cont.)
The main geodetic services of CORS network at the
National Land Agency is for the primary source for control
surveys of cadastral mapping.
It is also possible to be used horizontal geodetic datum.
JRSP is built to simplify and accelerate the achievement
of orderly land, increase productivity and accuracy, as
well as improving the quality of public services in the field
of surveying, measurement, and mapping.
Users
The main users of CORS network at the National Land
Agency are all of regencies and provinces National
Land Agency, Indonesia.
It also can be used to some users (individual, private
and national office) who get approval from National
Land Agency office to access JRSP (real time observation
or post observation).
It is also used part of national network for scientific
activities such as plate tectonic studies, datum
maintenance etc.
Issues to be Resolved
Applied datum in Indonesian are Bessel 1941,
Indonesian Datum 1974 (ID’74) and recently
National Geodetic Datum (DGN95) which is
geocentric by associating to the International
Terrestrial Reference Frame (ITRF) and the World
Geodetic System (WGS84) as a reference
Ellipsoid.
Issues to be Resolved (Cont.)
The parameters of National Geodetic Datum (DGN) 1995
are semi major axis (6378137.000 m) and semi minor axis
(6356752.3142 m), and flattening (f) where 1/f is
298.257223563 m.
The National Geodetic Datum (DGN95) is used for national
reference frame, survey and mapping in several offices such
as in the National Land Agency, Geospatial Information
Agency, national private companies and so on.

In the area there is an open (rice) which is

areas, sometimes also need to be
