What does EBL and VRM mean?
The variable range marker (VRM) and the electronic bearing line (EBL) measure the distance and bearing from your boat to a target object.
What is the function of variable range marker?
VRM stands for Variable Range Marker. This function provides an accurate measurement of range to targets. Press the [VRM] button to enable the VRM function. Adjust the VRM ring so it rests on the inside edge of the target.
What is the purpose of EBL?
EBL is an acronym for Electronic Bearing Line. It is used to determine the bearing from your present location to a specific target. Use the EBL function to bisect the target and see it’s bearing in the EBL readout display.
What is heading marker in radar?
The heading marker changes its direction according to the ship’s heading. If the TRUE motion is used, own ship and other moving targets move according to their course and speed. Fixed targets such as landmasses appear as stationary echoes.
What’s VRM mean?
voltage regulator module
VRM stands for voltage regulator module. Some modern CPUs and GPUs (aka graphics cards) use VRMs to control and lower the voltage (V) sent to these components in order to avoid exceeding their maximum voltage capabilities. VRMs are especially important for overclocking a CPU or GPU.
What is the use of EBL and VRM?
The electronic range line (EBL) and variable range marker (VRM) allow quick measurements of range and bearing to vessels and landmasses within radar range. Ranges to radar targets are very accurate; precise bearings require more care because they are dependent upon knowledge of your vessel’s heading.
What is range marker?
Two upright markers that may be lighted at night and placed so that, when aligned, the direction indicated assists in piloting. They may be used in amphibious operations to aid in beaching landing ships or craft.
What is the use of EBL in a radar?
What is EBL radar?
Radar. Electronic Bearing Line (EBL) •The electronic bearing line (EBL) is a radial line extending from the origin (own ship) that can be set to any bearing. • It can be used for ascertaining the relative bearing of a target.
What is maritime EBL?
• The electronic range line (EBL) and variable range marker (VRM) allow quick measurements of range and bearing to vessels and landmasses within radar range.
What is BCR and BCT?
BCR (Bow Crossing Range) and BCT (Bow Crossing Time) of two targets out of all tracked targets.
Why do ships have two radars?
Marine radars are X band or S band radars on ships, used to detect other ships and land obstacles, to provide bearing and distance for collision avoidance and navigation at sea. Therefore, displays can often overlay an electronic GPS navigation chart of ship position, and a sonar display, on the radar display.
How is the variable range marker usually adjusted for accuracy?
8-33D3: How is the variable range marker usually adjusted for accuracy? The minimum and maximum ranges are aligned with the matching fixed range ring. Adjusting the frequency of the VRM oscillator at the maximum range. Adjusting the frequency of the VRM oscillator at the minimum range. Adjusting the readout to match at the median range ring.
When does a variable range over the elements of a set?
When a variable ranges over the elements of a set (i.e., a variable of type :SET), this set also must be defined and given a name. A set definition is a sentence of the form (defset[setname] [type] [list of values]), where:
What is the use of variable range in programming?
These variables are very useful in complex programming and automation. Often variable range is used with the set statements and range method. Set statements are used to set a variable to a range of particular size and range property method is used to get the values already in that range or to replace them with another value.
What is a range variable in VBA?
Like every other variable Range in VBA, the variable is also a variable, but it’s an “Object Variable” we use to set the reference of the specific range of cells. Like any other variable, we can give any name to the variable, but the data type we assign to them should be a “Range.”
