COGO calculation
methods
Distances and
azimuths
COGO
COGO is an application program to perform coordinate geometry calculations such
as
e coordinates of points. e distances between points.
* bearings between points.
The calculations can be made from
e existing point data in the job, known distances or known azimuths.
* manually occupied points.
* entered coordinates.
Changing coordinates of a point which has been previously used in COGO does not
result in the point being recomputed.
The COGO calculation methods are:
e Inverse. e Arc calculations.
e Traverse. * Shift, Rotate & Scale (Manual)
e Intersections. e Shift, Rotate & Scale (Match Pts)
e Line calculations. e Area Division
Type of distances: The choices are
* Ground
e Grid
e Ellipsoidal
Type of azimuths: The azimuths are grid azimuths relative to the local grid.

Description
Access
COGO
Match Common
Points (n)
The COGO calculation shift, rotate & scale (match pts) applies shifts and/or rotation
and/or scale to one or several known points. The shifts and/or rotation and/or scale
are calculated from selected points using a 2D Helmert tranformation.
The number of pairs of points matched determines whether the shift, rotation and
scale values are computed.
Refer to "2.2 Accessing COGO" to access COGO Match Common Points (n).
This screen provides a list of points chosen from the active job. The points are used
for the determination of the 2D Helmert transformation. Unless there is no pair of
matching points in the list all softkeys are available.

Description
Requirements to

formation
Requirements for

Coordinate system
determination
methods
Overview
GPS measured points are always stored based on the global geocentric datum
known as WGS 1984. To convert the WGS 1984 coordinates into local coordinates
a coordinate system needs to be created. Part of the coordinate system is the trans-
formation used to convert coordinates from the WGS 1984 datum to the local datum.
The Determine Coordinate System application program allows:
e the parameters of a new transformation to be determined.
e the parameters of an existing transformation to be recomputed.
To determine a transformation it is necessary to have common control points whose
positions are known in both WGS 1984 coordinates and local coordinates. The more
points that are common between datums the more accurately the transformation
parameters can be calculated. Depending on the type of transformation used, details
about the map projection, the local ellipsoid and a local geoidal model may also be
needed.
e The control points used for the transformation should surround the area for
which the transformation is to be applied. It is not good practice to survey or
convert coordinates outside of the area covered by the control points as extrap-
olation errors may be introduced.
e When a geoid field file and/or a CSCS field file is used in the determination of a
coordinate system, the control points for the calculation must fall within the areas
of the field files.
With one common control point, it is possible to calculate a Classic 3D transforma-
tion, as long as the rotations and the scale parameter are fixed. Such a transforma-
tion fits perfectly in the vicinity of the common control point, but is degraded by the
distance from that point.
Two different methods for determining a coordinate system are available:

The Reference Line application program can be used for the following tasks:
e Measuring to a line/arc where the coordinates of a target point can be calculated
from its position relative to the defined reference line/arc.
e Staking to a line/arc where the position of a target point is known and instructions
to locate the point are given relative to the reference line/arc.
* Gridstaking a line/arc where a grid can be staked relative to a reference line/arc.
Measuring and staking out of points is possible for <R-Time Mode: Rover> and <R-
Time Mode: None>.
Heights and positions are always taken into account. Points must have full coordi-
nate triplets.
Reference point: |The term reference point is used in this chapter to refer to the
point from which the perpendicular offset from the reference
line/arc, to the target point, is measured. Refer to paragraph "
Defining a reference line/arc" and the diagrams for further
explanation.
Target point: The design point.
For measuring to a reference line, this is the point with the coor-
dinates of the current position and the designed or calculated
height.
For staking or grid staking to a reference line, this is the point to
be staked.
Measured point: The current position.
A reference line can be defined in the following ways:
e Two known points
* One known point, an azimuth, a distance and a gradient
* One known point, an azimuth, a distance and a difference in height
A reference arc can be defined in the following ways:
+ Two known points and a radius
«Three known points
The chainage of the start point of a reference line/arc can be defined.
<Azimuth:> is used throughout this chapter. This should always be considered to

Reference Plane
The Reference Plane application program can be used for the following tasks:
+ Measuring points to calculate and store the perpendicular distance to the plane.
+ Viewing and storing the instrument and/or local coordinates of the measured
points.
+ Viewing and storing the height difference from the measured points to the plane.
Planes can only be computed with grid coordinates.
Reference planes are created using a right hand system. For two points defining a
plane, a vertical plane is used. A reference plane is defined with the X axis and the
Z axis of the plane. The Y axis of the plane defines the positive direction of the plane.
e For GPS1200 the Reference Plane application program is only applicable for
tilted plane definitions.
+ For TPS1200, the Reference Plane application program is also applicable for
vertical plane definitions.
Any number of points define the plane. The axis of the tilted reference plane are:

Observation times for dual frequency receivers
The following table is an approximate guide as it is impossible to quote observation
times that can be fully guaranteed. The quoted observation times are based on tests
in mid-latitudes under normal ionospheric disturbance with a dual frequency
receiver.

Observation times for single frequency receivers
Providing recommendations for required observation times is more difficult for single
frequency receivers than for dual frequency receivers. The following table is an
approximate guide since it is impossible to quote observation times that can be fully
guaranteed. A minimum of five satellites above 15° and a GDOP < 8 must be avail-
able.
As arule of thumb the baseline observation time should be 5 min per km of the base-
line length with a minimum time of 15 min.

10 Survey - Auto Points
10.1 Overview
Description Auto points is used to automatically log points at a specific rate. Additionally, indi-
vidual auto points can be stored outside the defined rate. Auto points are used in
real-time or post-processed moving applications to document the track which was
walked or driven along. Auto points are logged between starting and stopping
logging of auto points form one chain. A new chain is formed each time logging of
auto points is started.
Auto points can be collected in the Survey application program. An Auto page is
visible when logging of auto points is active.
Up to two offset points related to one auto point can be logged. The offset points can
be both to the left or right and they can be coded independently of each other and of
the auto points.
Ee Logging of auto points is possible for <R-Time Mode: Rover> and <R-Time Mode:
None>.

Auxiliary points
Hidden points cannot be measured directly by GPS. This is because they can not be
physically reached or because satellites are obstructed, for example by trees or tall
buildings.
« A hidden point can be calculated by measuring distances and/or azimuths to the
hidden point using a hidden point measurement device. Or for distances a tape
may be used.
e Additional auxiliary points may be manually occupied.
*« Bearings may be computed from previously occupied points.
A hidden point measurement device can be attached to the receiver such that the
measurements are automatically transferred to the receiver.
Changing coordinates of a point which has been previously used in hidden point
measurements does not result in the hidden point being recomputed.
Hidden point measurements are possible for <R-Time Mode: Rover> and <R-Time
Mode: None>. For <R-Time Mode: None> the hidden point can be calculated in
LGO.
A hidden point can be measured by
«Bearing and distance e Chainage and offset

Heights are taken into account if configured. Refer to the GPS System Field Manual
for information on configuring height offsets.
Refer to the GPS System Field Manual for information on how to configure hidden
point measurements.
<Azimuth:> is used throughout this chapter. This should always be considered to
also mean <Bearing:>.
Auxiliary points are used to compute azimuths required for the calculation of hidden
point coordinates. Auxiliary points can be points existing in the job or they can be
