Flex Mode
A Novariant proprietary process that allows the GeoSteer system to fall back to an
alternative, less accurate correction source when communications from the
primary source has been interrupted. This allows AutoSteering operations to
continue uninterrupted at a lower accuracy levels until the primary source has
been restored.
Frequency
The number of occurrences of a repeating event per unit time. For example waves
per second.
GLONASS
A worldwide satellite navigation system operated and maintained by the Russian
government. The full orbital constellation consist of 24 satellites.
GNSS
Global Navigation Satellite System. This is a term that includes GPS, GLONASS,
BeiDou (BDS) and Galileo satellites systems which are used to provide navigation
information to mobile receivers.
GPS
Global Positioning System
—A worldwide satellite based navigation system
managed by the United States Department of Defense that uses up to 32 satellites.
GSM
Global Standard for Mobile Communications
—A radio communication
technology utilizing time division multiple access developed by European
countries and operated at both cellular and PCS frequencies.
HDOP
Horizontal Dilution Of Precision
—This is a term that describes the horizontal
(latitude/longitude) quality of a GPS position based on the satellite geometry that
is used to calculate it. The lower the number the better the quality.
Hotspot
This is a WiFi network access point.
HTTP
Hyper Text Transfer Protocol
—This is a computer language used to
communicate over web pages.
Hz
Hertz
—This is a measure of actions per second (ex. cycles per second).
INX
This is a Novariant proprietary communication protocol for transmitting Base
Station correction data. This format is only used by Novariant devices.
IP
Internet Protocol
—This is a communication protocol used primarily by devices
sending and receiving information across the internet or private networks.
ISO
International Organization for Standardization—This is an organization which
develops and publishes international standards to insure that products or services
are safe, reliable and of good quality.
L1
The GPS radio signals that are transmitted at the 1575.42 MHz carrier frequency
which includes the C/A and P-code.
L2
The GPS radio signals that are transmitted at the 1227.60 MHz carrier frequency
which comprises of the P-code only.
Latitude
This is a geographic coordinate that specifies the north-south position of a point
on the Earth's surface.
LED
Light-Emitting Diode
—This is a semiconductor light source.
Longitude
This is a geographic coordinate that specifies the east-west position of a point on
the Earth's surface.
MDN
Mobile Directory Number
—The actual phone number one would dial to reach
a specific mobile device. This number can be kept by the operator.
MDU
Mechanical Drive Unit
—This is a generic term to describe a device that is
attached to the steering wheel of a vehicle to allow the an GeoSteer system to
control which direction to steer the vehicle.
MFWD
Mechanical Front Wheel Drive
—This indicates that the front wheels of a
standard tractor cab be engaged and be used to pull the tractor forward while the
rear axles are pushing. This in effect turns the vehicle into a four wheel drive.
MIN
Mobile Identification Number
—This is also known as the Mobile Subscription
Identification Number (MSIN) and refers to the 10-digit unique number that a
wireless carrier uses to identify a mobile device. This number is given by the
wireless carrier.
