Import Astrolabe 201 Vehicle Gps Tracker — Buy in Bulk from Supplier in China

The Astrolabe 201 is a quad-band GSM vehicle GPS tracker built around a 22-channel GPS chipset with dual antenna redundancy, an 800mAh backup battery, and a 16-pin IO interface. It operates across GSM 850/900/1800/1900 MHz with GPRS Class 12/10/8 and TCP/UDP protocols, achieving a tracking sensitivity of -165dBm and position accuracy of 5 metres. The unit measures 89 x 93 x 22mm, weighs 108g, and runs on 9V-39V vehicle power across a working temperature span of -45°C to 70°C. Shenzhen Tomo Tek Co., Ltd. packages this unit as 1 piece per colour box and 20 pieces per carton, with each colour box measuring 155 x 112 x 63mm.

The tracker incorporates both a built-in ceramic high-gain GPS antenna and an external antenna port, with automatic failover if the external antenna is cut. An acceleration sensor detects hard braking, hard acceleration, and sharp turns, triggering buzzer alerts for driver behaviour monitoring. The 16 IO configuration includes 4 high inputs (ACC, anti-theft alert), 4 low inputs (anti-remove, SOS), 4 outputs (remote door control, fuel cut-off), 4 self-defined ports, plus dedicated microphone, loudspeaker, and USB interfaces. The 2MB memory supports data logging during GSM gaps. Standard industry practice for fleet-grade trackers of this class is an IP53 or higher environmental seal, though buyers should confirm the exact ingress protection rating with the supplier.

Typical buyers include fleet operators, vehicle finance companies, and logistics providers needing real-time tracking, geofencing, and remote immobilisation. The two-way audio, SOS emergency button, and over-the-air firmware upgrade capability suit security-conscious deployments. The -165dBm tracking sensitivity supports urban canyon and partial canopy operation. Buyers should verify CE and FCC certificate scope covers their target markets, and confirm whether the web-based tracking platform and mobile apps incur separate subscription fees. The 800mAh battery provides limited standalone operation; confirm expected standby duration during main power disconnection.

Shenzhen Tomo Tek Co., Ltd. maintains a registered address at A1309, Jinlian Building, Qianjin 2nd Road, Xixiang, Bao'an District, Shenzhen, 518100, Guangdong, China. The supplier holds a Harbor trust tier on the platform, with a response rate currently showing 0.00 and average response hours at zero, which suggests either a new listing or a profile that has not yet generated measurable engagement. No verified trade data, factory audit results, or years-in-business figure is present in the source material. Buyers should treat the supplier as an unverified contact and conduct standard due diligence before advancing to sample or trial orders.

The listing presents itself as a manufacturer or brand owner of the Astrolabe 201 tracker, given the model-specific naming and detailed technical documentation. However, the source does not confirm factory ownership, R&D capacity, production volume, or whether Shenzhen Tomo Tek operates as an OEM/ODM house, trading company, or brand licensee. The product carries CE and FCC markings, but the listing does not state the certifying body or test report numbers. Buyers should request ISO 9001 or IATF 16949 quality system evidence if available, and verify that the declared certificates are current and applicable to the exact SKU being quoted.
