GS2 Display—StarFire iTC

NOTE: TOGGLE button allows operator to change the way latitude and longitude are displayed from degrees/minutes/seconds to decimal degrees.

•Altitude: displays height of receiver, measured from top of dome, in feet (meters) above sea level.

•GPS course: Displays direction of travel, in degrees relative to true north (zero degrees) as measured by receiver. Angle is measured in clockwise direction

NOTE: Course and speed normally show small speeds and various courses even when machine is not moving.

•GPS speed: displays ground speed of machine in miles per hour (kilometer per hour) as measured by receiver.

•GPS Accuracy Indicator (GPS AI): GPS AI gives indication of GPS position accuracy achieved by receiver, and is displayed as a percentage (0-100%)

When receiver is initially powered, GPS AI will display 0%. As receiver acquires satellites and calculates a position, GPS AI will increase as accuracy improves. Acceptable guidance performance for Parallel Tracking and AutoTrac is achieved when GPS AI displays 80% or greater. This may take up to 20 minutes. GPS accuracy is affected by many factors. If 80% accuracy or greater is not achieved within 25 minutes, consider the following possibilities:

•Unobstructed view of sky – trees, buildings, or other structures may block receiver from receiver signals from all available satellites.

•L1/L2 signal to noise ratio (SNR) – radio interference from 2-way radios or other sources may cause low SNR (check satellite button – Graph)

•Satellite position in sky – poor GPS satellite geometry can reduce accuracy (check satellite button – SkyPlot)

•Number of satellites above elevation mask – this is the total number of GPS satellites available to receiver that are above 7 degrees elevation mask (check satellite button – SkyPlot).

•Number of satellites in solution – this is total number of satellites that are being used by receiver to calculate a position (check satellite button– SkyPlot).

•GPS Signal Quality: Displays quality of signals being received from constellation of GPS satellites.

•Differential Signal Quality: Displays quality of differential correction signal being received by receiver.

•TCM (Terrain Compensation Module):

–Roll Angle: Is both a graphical and numerical representation of amount of roll TCM is measuring, relative to calibrated zero degree reference. A positive roll angle means vehicle is rolled to right (depicts what horizon would look like from cab).

–Yaw Rate: This gives a graphic representation and a numeric figure for amount of rotation TCM is measuring. Positive yaw rate means vehicle is turning to right.

The fore/aft value is the distance that receiver is located from pivot point of tractor.

On some AutoTrac-equipped vehicles, fore/aft value will be automatically detected and entered during power up.

•Fore/Aft value is shown and input box is disabled – value has been automatically set and cannot be changed. The value shown may not be the exact distance that the receiver is located from pivot point of tractor, but the best Fore/Aft value for AutoTrac.

•Fore/Aft value is shown and input box is enabled – value must be entered manually.

To enter Fore/Aft value:

• Select FORE/AFT input box

• Enter value using numeric keypad

Height

Height is measured from ground to top of StarFire Dome. Select input box and use numeric keypad to enter height.

IMPORTANT: Under or over compensation for vehicle roll angles will occur if height is incorrectly entered during setup.

Example: On a 10 degree slope with a StarFire height error of 30.5 cm (12 in.) will result in a position offset of 5 cm (2 in.) on ground).

Factory default setting is “126”. On some AutoTrac-equipped vehicles, height value will be automatically detected and entered during power up. Because this dimension is critical for proper operation of TCM and can vary due to vehicle configuration and tire sizes, operator should still measure actual distance

to be entered each time TCM is installed on a different vehicle.

NOTE: Use chart for example StarFire Height values.

Chart figures are approximate heights.

Calibration Surface

IMPORTANT: Vehicle must be on a hard, flat level

	surface for calibration. If TCM is not
	calibrated on a level surface or TCM
	mounting angle is not level in relation
	to vehicle angle (StarFire mounting
	bracket or vehicle cab being slightly
	offset, uneven tire pressures from one
	side to other, etc.) operator may see
	offset during operation. This offset
	could look like a consistent skip (A) or	A—Skip
	overlap (B) in pass-to-pass operation.
		B—Overlap
	To eliminate offset, re-calibrate on a
	level surface, drive down a pass, turn
	around and drive down same pass in
	opposite direction. If vehicle does not
	follow same pass, measure offset
	distance and enter in implement offset.
	After initial calibration of TCM, it is not
	necessary to calibrate again unless
	TCM angle in relation to vehicle has
	changed. For example, tire pressure has
	been lowered on one side of vehicle
	causing vehicle angle in relation to
	ground to change.

Calibration Procedure:

1.Press CALIBRATION button.

2.Park vehicle on a hard, level surface and come to a complete stop (cab is not rocking).

3.Press ENTER button.

4.Calibrating Status bar will appear. Once status reaches 100% it will automatically advance.

5.Turn vehicle 180 degrees to face opposite direction. Ensure that tires are in proper location for fixed or floating front axle and vehicle has come to a complete stop (cab is not rocking).

6.Press ENTER CALIBRATION button.

7.Calibrating Status bar will appear. Once status reaches 100% it will automatically advance.

8.Once finished, a calibration value will be displayed. 0 degree calibration value is the difference between factory calibration value and actual calibration value which was just determined.

NMEA Strings

NMEA String Data – Utilizing a third party GPS receiver or utilizing a StarFire iTC

National Marine Electronics Association (NMEA) has developed a specification that defines the interface between various pieces of electronic equipment.

One of the most important NMEA sentences include the GGA which provides the current Fix data, the RMC which provides the minimum GPS sentences information, and the GSA which provides the Satellite status data.

GGA - essential fix data which provide 3D location and accuracy data.

GGA STRING EXAMPLE:

$GPGGA,123519,4807.038,N,01131.000,E,

1,08,0.9,545.4,M,46.9,M,,*47

Where:

GGA	Global Positioning System Fix Data
123519	Fix taken at 12:35:19 UTC
4807.038,N	Latitude 48 deg 07.038’ N
01131.000,E	Longitude 11 deg 31.000’ E
1	Fix quality:
	0	= invalid
	1	= GPS fix (SPS)
	2	= DGPS fix
	3	= PPS fix
	4	= Real Time Kinematic
	5	= Float RTK
	6	= estimated (dead reckoning)
	7	= Manual input mode
	8	= Simulation mode
08	Number of satellites being tracked
0.9	Horizontal dilution of position
545.4,M	Altitude, Meters, above mean sea level
46.9,M	Height of geoid (mean sea level) above WGS84

GSA - GPS DOP and active satellites. This sentence provides details on the nature of the satellite constellation fix. It includes the numbers of the satellites being used in the current solution and the DOP. DOP (dilution of precision) is an indication of the effect of satellite geometry on the accuracy of the fix. It is a unitless number where smaller is better. For 3D fixes using 4 satellites a 1.0 would be considered to be a perfect number, however for overdetermined solutions it is possible to see numbers below 1.0.

There are differences in the way the PRN’s are presented which can effect the ability of some programs to display this data. For example, in the example shown below there are 5 satellites in the solution and the null fields are scattered indicating that the almanac would show satellites in the null positions that are not being used as part of this solution. Other receivers might output all of the satellites used at the beginning of the sentence with the null field all stacked up at the end. This difference accounts for some satellite display programs not always being able to display the satellites being tracked. Some units may show all satellites that have ephemeris data without regard to their use as part of the solution but this is non-standard.

GSA String Example

$GPGSA,A,3,04,05,,09,12,,,24,,,,,2.5,1.3,2.1*39

Where:

GSA	Satellite status
A	Auto selection of 2D or 3D fix (M = manual)

SKY PLOT tab

Illustrates where satellites are in relation to vehicles receiver. This allows operator to look at satellite geometry.

Reading Satellite Sky Plot

•Sky Plot is fixed so that North is always at top.

•Satellites are displayed as their satellite ID number that correspond to Satellite Tracking Chart located right of Sky Plot

–Red – indicates satellite is in search mode

–Blue – indicates satellite is being tracked

–Green – indicates satellite is OK (being used for corrections)

•Sky Plot consists of 3 concentric rings depicting 0, 30, and 60 degrees of elevation with directional crossbar intersection representing 90 degrees of elevation.

•Grey radial lines extending from center of Sky Plot represent azimuth. They are spaced 30 degrees apart and represent 30 and 60 degrees.

•Directional crossbar representing North, South, East, and West also represent azimuth at 0, 90, 180, and 270 degrees.

•W1 and W2 (WAAS/EGNOS) satellites and inmarsat satellites are not shown in Sky Plot.
