RNSS
RNSS stands for Regional Navigation Satellite System. It refers to satellite-based navigation systems that are designed to provide positioning, navigation, and timing services over a specific regional area, rather than globally. Advantages: Higher Accuracy: RNSS can provide more precise positioning services within the designated regional area. Improved Availability: It can offer better signal availability in […]
RMSE
Root Mean Square Error (RMSE) is a way to measure how far off predictions or estimates are from the actual values. It gives you an idea of the average size of the errors in a set of measurements, but with more focus on larger errors. Here’s how it works: Calculate the error: For each prediction, […]
RMS
RMS (Root Mean Square) is a statistical measure used to calculate the average magnitude of a set of values, especially for signals that fluctuate between positive and negative values. It is calculated by taking the square root of the average of the squares of the values. Applications: Electrical Engineering: To calculate effective voltage or current […]
Ranging accuracy
Ranging accuracy refers to the precision with which the distance between two points (typically between a satellite and a receiver) can be measured in a positioning or navigation system. It is a critical factor in systems like GPS, GNSS, and radar, where the goal is to accurately determine the distance between the receiver and the […]
Quartz vibrating Beam Accelerometers
The quartz vibrating beam accelerometer is designed based on the vibrating beam principle. It typically utilizes a vibrating beam made of quartz material (usually a small quartz beam) to sense acceleration. The frequency of the vibrating beam changes with acceleration, and this change can be detected by an electronic system. Basic Operating Principle: Vibrating Beam: […]
Quartz accelerometer & Quartz vibrating Beam Accelerometer
The Quartz Accelerometer and Quartz Vibrating Beam Accelerometer share some similarities in their working principles, but they differ fundamentally in structure and measurement methods. Both are based on quartz material sensors, but their designs and application fields are distinct. Quartz Accelerometer As previously mentioned, the Quartz Accelerometer primarily utilizes the piezoelectric effect to measure acceleration. […]
Quartz accelerometer
The quartz accelerometer primarily uses the piezoelectric effect to measure acceleration. When the quartz crystal is subjected to acceleration or force, it undergoes slight deformation, generating electrical charges. These charge changes can be used to measure the magnitude and direction of the acceleration. Basic Operating Principle: When the object accelerates, the internal structure consisting of […]
Quartz resonating beam accelerometer
The quartz resonating beam accelerometer is designed based on the vibrating beam principle. It typically uses a vibrating beam made of quartz material (usually a small quartz beam) to sense acceleration. The frequency of the vibrating beam changes with acceleration, and this change can be detected by an electronic system. Basic Operating Principle: Vibrating Beam: […]
PZ-90 GS
The geodetic coordinate system established by Russia. The origin of its coordinate system is located at the Earth’s center of mass, with the Z-axis pointing towards the Protocol Earth Pole (CTP) defined by BIH1984.0, the X-axis pointing towards the intersection of the zero-degree meridian of BIH1984.0 and the CTP equator, and the Y-axis following the […]
Precision
Precision refers to the consistency of the system’s output, specifically the distribution of errors across multiple measurements. A system with high precision may produce very similar results across several measurements, but these results do not necessarily align with the true value.
