Quectel L96-M33 miniature multi-system GNSS module with patch antenna

09.01.2020

The new Quectel L96-M33 module is capable of working with the signals of four satellite constellations: GPS L1 1575.42MHz C/A Code, GLONASS, BeiDou and Galileo, which improves the quality of positioning in urban environments. Thanks to a miniature chip antenna, the module can be successfully used in wearable equipment, where the dimensions of the device are a determining factor.

L96-M33 has improved efficiency when receiving weak signals and high sensitivity: -165 dBm in tracking mode and -148 dBm in capture mode. It is possible to connect an external antenna.

The receiver uses a built-in auxiliary system to quickly determine the position of AGPS EASY. This technology reduces the time to first detection (TTFF). Additionally, the module stores data on the movement of satellites in its memory and, based on them, makes predictions for up to 3 days, which allows the module to quickly determine the location in low-power conditions.

AlwaysLocate technology allows you to adjust the on / off time and strike a balance between positioning accuracy and power consumption.

To control the module, you can use the UART and I2C interfaces (NMEA 0183 and PMTK protocols). The supply voltage of the L96-M33 is in the range from 2,8 to 4,3 V. The current consumption is 20 mA in tracking mode and 25 mA in search mode (GPS + GLONASS). In power-saving AlwaysLocate mode, consumption is reduced to 2,8 mA. Operating temperature range -40...85°C.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
