nanosecond is equal to 30 cm.

In what year does GLONASS satellite system declared fully operational?

What satellite system provides global search and rescue function?

What is the meaning of MEO in GNSS?

Master Station adjust the satellite's orbit parameters and on-board high precision clocks when necessary to maintain accuracy.

What is the contributing source for Error Range of ±0.5 m?

What is the accuracy of NAVIC satellite system?

Who develop echo sounder?

The control segment comprises of a ground-based network of master control stations, data uploading stations, and monitor stations.

L1C "Fourth Civilian GPS Signal" has a bandwidth of 1575.45 MHz.

How many satellite and spares does * GPS satellite system have?

What year Echo sounder develop?

On what specific date that BeiDou Navigation Satellite System started providing global services?

What is the term used for approximation distance between satellite and a GNSS receiver?

What is the meaning of NAVSTAR in GNSS satellite system?

In what year does GPS was initially launched for military use, but opened up to civilian use?

What is the term used for the point of the orbit closest to Earth?

adjust the satellites' orbit parameters and on-board high-precision clocks when necessary to maintain

How much error range does Receiver * Noise have?

Dgps

The point in the moon's orbit where it is farthest from the earth is called

monitor the satellites' signal and status, and relay this information to the master control station

Consists of GNSS satellites, orbiting about 20,000 km above the earth. Each GNSS has its own constellation of satellites

User segment consists of GNSS antennas and receivers used to determine information such as position, velocity, and time

It is a way of radio signals are transmitted from one point to another inside the Earth's atmosphere or free space.

To determine accurate positions, we need to know the range to the satellite. This is the direct path distance from the satellite to the user equipment The signal will "bend" when traveling through the earth's atmosphere. This "bending" increases the amount of time the signal takes to travel from the satellite to the receiver. Since the computed range contains errors and is not exactly equal to the actual range, we refer to it as a "pseudorange"

GPS works through a technique called

At what speed does GPS satellite travels above the Earth?

Sonar originally an acronym for?

used to build up an image of a large area of the sea bed.

microsecond is equal * to 10,000 nanoseconds.

type of Echo sounder

it uses digital methods in measuring time delay of return pulses and a digital analogue display

What is the meaning of GEO in GNSS?

measuring the depth to the ocean floor directly underneath the ship.

Receivers need at least 4 satellites to obtain a position. If more are available, these additional observations can be used to improve the position solution GNSS signals are modulated by a unique pseudorandom digital sequence, or code. Each satellite uses a different pseudorandom code Receivers know the pseudorandom code for each satellite. This allows receivers to correlate (synchronize) with the GNSS signal to a particular satellite

Ground antenna uploads any changes in satellite status back to the satellites.

What is the contributing source for Error Range of ±5 m?

uploads any change in satellite status back to the satellites

It is a term used for measuring the distance not angles.

how many satellite to give us position in gps?

What is the inclination angle of GLONASS satellite system?

A DGPS for GPS can increase accuracy by about a thousandfold, from approximately?

How much is the altitude of GALILEO satellite system?

record depth on a specially treated paper held between 2 rollers moving at a uniform speed over a grounded plate.
