Seamless Tracking Without Interruption with Jimiiot VL101G Vehicle Tracker


An underground parking lot is a location where the positioning signal of a tracking system is difficult to penetrate. These areas are typically constructed of concrete and steel structures, which greatly impede the transmission of GPS signals, resulting in inaccurate output of real-time vehicle location trajectories by onboard tracking devices.

  • Signal Interference: Thick concrete walls and multiple layers of underground parking structures significantly weaken GPS signals, leading to signal loss or degradation.
  • Multipath Effects: Signal reflections on the surfaces inside the parking lot generate multipath interference, resulting in inaccurate and inconsistent position estimations.
  • Limited Line of Sight: The lack of direct line of sight to GPS satellites further exacerbates signal attenuation, especially in lower levels or enclosed portions of the parking lot.
  • Environmental Factors: Electromagnetic interference from other environmental factors such as electrical equipment, ventilation systems, and structural obstacles also affects signal quality.

The subterranean nature of parking garages poses significant challenges for tracking systems, particularly in terms of signal reception and transmission. This results in obstacles for tracking systems to deliver precise and uninterrupted location data within underground parking facilities. As a consequence, real-time monitoring of vehicle positions becomes unreliable, creating operational hurdles and potential safety concerns for both parking facility operators and vehicle owners. Addressing these issues necessitates practical and effective solutions capable of overcoming signal attenuation and ensuring consistent tracking performance in underground environments.

  • Strong Anti-Interference Capability: Dual-frequency GPS technology enhances positioning stability and accuracy, effectively resisting signal interference.
  • Continuous Tracking: INS-aided tracking ensures continuous vehicle tracking even in environments with weak or no GPS signals.
  • Safety and Reliability: The waterproof and dustproof design protects the device from external environmental factors, providing reliable positioning and tracking services.

Overcoming Signal Challenges in Underground Parking

One of the primary challenges faced by vehicle trackers operating in underground parking lots is signal attenuation, which compromises the accuracy and reliability of location data. However, the VL101G employs several strategies to mitigate these signal issues and ensure seamless tracking performance.

Firstly, the VL101G’s robust multi-positioning system enables it to maintain connectivity with multiple satellite networks, reducing reliance on a single source of positioning data. This redundancy minimizes the impact of signal blockage or interference common in underground environments.

Additionally, the VL101G leverages its INS aided tracking feature to fill gaps in satellite coverage. In situations where GPS signals are weak or unavailable, the tracker seamlessly transitions to inertial navigation mode, utilizing onboard sensors to estimate vehicle movement and position accurately.

Furthermore, the VL101G’s design includes an IP66-rated waterproof and dustproof enclosure, enhancing its durability and resilience to environmental factors encountered in underground parking facilities and adverse weather conditions. Even in inclement weather, the VL101G maintains its ability to provide accurate positioning, ensuring reliable tracking performance regardless of external circumstances.

By integrating these advanced features and technologies, the Jimiiot VL101G vehicle tracker effectively overcomes signal challenges in underground parking environments, ensuring the delivery of precise and continuous location tracking data, even in areas with weak or obstructed satellite signals.

The key distinction from the VL106 lies in this product’s ability to instantly provide accurate positioning trajectories even when initiated and driven out from weak or no-signal areas. Conversely, the VL106 is unable to present genuine trajectories during this initial stage and only depicts linear paths.
