Accurate GPS Receiver Antenna for Agriculture, Deformation, Navigation and Locating

This antenna is designed for a wide range of applications, including Beidou 2, GPS, and GLONASS navigation. It offers exceptional performance and durability, making it suitable for use in a variety of industries, such as geodesy, agriculture, and oceanography, where precise navigation and locating are critical.

The antenna operates within a frequency band of 1166MHz-1278MHz and 1521MHz-1608MHz, covering the working frequencies of BDS (B1A, B1I, B1C, B2I, B2a, B2b, B3A, B3AE, B3Q), GPS (L1, L2, L5), GLONASS (G1, G3), and GALILEO (E1, E5a, E5b, E6). It also supports SBAS (L1, L5) and QZSS (L1, L2, L5, L6) signals.

The antenna features a 50Ω impedance and a right-hand circular polarization (RHCP) mode, providing a 360-degree horizontal covering angle. Its maximum gain is rated at ±5dBi, and the antenna's axial ratio and phase center error are within ±2mm, ensuring precise measurement results.

To enhance reliability and accuracy, the antenna is equipped with a low-noise amplifier (LNA) that provides a gain of 40dB±2dB and a noise factor of ≤2dB. The in-band flatness is maintained within ±2dB, and the output 1dB compression point is greater than or equal to 0dBm.

The antenna operates on a DC voltage of 3.3-16V and a typical current consumption of ≤45mA. The differential delay is ≤5ns, ensuring accurate time synchronization.

Physically, the antenna measures approximately 150 x 58.4mm (5.9 x 2.3 inches) and is designed for bottom mounting using a coarse thread 5/8in-11 with a depth of 12-14mm (0.47-0.55 inches). The connector type is TNC-K.

The antenna is designed to withstand a wide range of environmental conditions, with an operating temperature range of -40°C to +85°C and a storage temperature range of -55°C to +85°C. It is also rated for 95% non-condensing humidity and meets the IP68 standard, meaning it is waterproof and dustproof, with a high compressive strength of 12.24kgf/cm².

The package includes the antenna, a mount, and a 5-meter cable, making it easy to set up and use. The antenna's small size, high gain, and excellent reception on low satellites ensure reliable data collection, even in obstructed areas.

In summary, this versatile antenna is an excellent choice for a wide range of navigation and positioning applications, offering high performance, durability, and ease of use.
