Jumpstar JS-UP26F-1
L1 Full-Constellation GNSS Positioning Module
JS-UP26F-1 is a high-performance L1-band GNSS module based on a standard precision GNSS platform, equipped with onboard FLASH storage for configuration retention. It delivers exceptional RF sensitivity and fast acquisition, with optimized tracking for non-line-of-sight & small-antenna scenarios.
Adopting ultra-low-power continuous tracking design, it ensures long battery life for asset trackers and portable devices. Integrated with LNA & SAW filter for maximum passive antenna sensitivity, it supports 4-system concurrent reception and maintains reliable positioning in challenging environments.
L1 full constellation, -166dBm tracking sensitivity, 10Hz update rate (18Hz single constellation), onboard FLASH, and ultra-compact 16.0×12.2×2.4mm size make JS-UP26F-1 ideal for battery-powered tracking and portable positioning applications.
