NTTIM GNSS Anti-Jamming Terminal Overview
The NTTIM Ultra-Miniature Satellite Navigation Anti-Jamming Terminal is an ultra-compact navigation device designed for applications such as unmanned aerial vehicles, electronic countermeasures, and communication base stations. With dimensions of 65mm×65mm×30mm, it enables in-situ replacement of most airborne or vehicle-mounted antennas. It achieves anti-jamming processing for GPS-L1/BDS-B1 frequency points against various interference types including broadband, narrowband, frequency sweeping, pulse, and combined interference. Integrating a 4-element antenna array, anti-jamming components, and a navigation receiver unit into a single unit, this product adopts a low-cost, miniaturized, and lightweight design. It caters to high-precision navigation requirements in complex electromagnetic environments, and delivers performance especially in the UAV sector.

NTTIM Compact Enclosure Mechanical Dimensions / Structural Profile
The physical envelope metrics of the chassis are defined by an absolute structural profile of 65mm×65mm×30mm±0.5mm, maintaining a lightweight configuration of 185g. Symmetrical integration across platforms is achieved through 4x Φ2.8mm through-holes positioned at a spacing grid layout of 59.7mm×59.7mm. This layout permits swift in-situ replacement of standard legacy airborne or vehicle-mounted passive antenna units.
