This article will outline critical updates to the Bullet line of antennas:
- The new Bullet 720
- Replacement Part Numbers
- EOL Trimble Buller Products
For many years the Trimble Bullet GPS Antennas have been market leaders. They are known to be rugged and reliable in harsh environments. But it's a new world. Threats to security and the need for speed push companies like Trimble to make advanced products.
Announcing the Bullet 720 Dual-Band Multi-GNSS Active Antenna.
What is the Trimble Bullet 720?
It's a ruggedized weatherproof dual-band (L1 & L5) multi-GNSS active antenna. It has a high out-of-band rejection filter and a built-in LNA. This compensates for feedline losses and provides improved performance in harsh GNSS environments.
Additionally, Bullet 720 uses the higher power L5 signals (twice the power of L1). Greater bandwidth and advanced signal design lower the risk of interference and improve multi-path protection.
The dual-band capability also allows GNSS receivers to compensate for ionosphere errors. As a result, there can be a reduction of the timing error under clear skies to a few nanoseconds.
Here's a summary of the key features in the Bullet 720:
- Dual Band (L1 and L5) Active Antenna with built-in LNA.
- Multi-constellation – GPS L1 & L5, Galileo E1 & E5, Beidou B1 & B2C, GLONASS G1 and IRNSS bands.
- High Gain, low noise, high out-of-band rejection.
- Built-in lightning protection that meets/exceeds handling IEC 61000-4 specifications.
- Ruggedized IP67 enclosure and supports extended temperature environments.
- Wide operating voltage range
What is different between the Trimble Bullet and the Trimble Bullet 720?
The critical difference is the support of the L5 band. The result? A reduction of the timing error under clear skies to a few nanoseconds.
New Part Numbers for the Trimble Bullet Antennas
The Bullet antenna has always been available in many forms to accommodate users requiring:
- various GNSS configurations,
- a TNC or F connector,
- or a 3.3v or 5 v input.
Trimble has introduced two new Bullet part numbers that will merge many of these variations into one part number to make things more simple. The new part is compatible with both 3.3v and 5.v input requirements and multiple GNSS constellations.
The new antennas are based on the same composite architectures and meet/exceed current specifications.
Trimble part number 101898-00 (TNC) will replace:
