In the field of modern medical care and emergency treatment, a portable oxygen concentrator with battery has become an indispensable device. It can efficiently extract oxygen from the air and provide patients with the necessary oxygen therapy support.
In GPS positioning systems, helical antennas are widely used due to their unique left-hand circular polarization characteristics, especially in the fields of drone PX4 flight control.
In high altitude or low temperature environments, the performance of the portable oxygen concentrator with battery may indeed be affected to a certain extent.
With the rise of plateau tourism and the increasing demand for work in high-altitude areas, the problem of oxygen supply in plateau environment has become increasingly prominent.
Its core lies in the clever use of carrier phase differential technology to achieve centimeter-level or even millimeter-level precise positioning.
Low power GNSS modules play a key role in many fields, especially in scenarios with strict energy consumption requirements, such as smart wearable devices, trackers, and IoT applications.
