Problem
Accurate absolute distance measurement, ultra‑stable time/frequency transfer, and high‑bandwidth optical communication are constrained by bulky, low‑precision, or line‑of‑sight limited technologies, restricting satellite formation flying, large‑scale structural monitoring, and precise Earth‑observation applications.
Solution
DORT (Dynamic Optical Ranging & Timing) delivers micrometer‑level absolute distance measurement, sub‑10⁻¹⁵ Allan‑deviation time and frequency transfer, and gigabit‑per‑second data links using purely optical methods. The technology is offered in modular products: DORT‑Space provides inter‑satellite ranging (µm accuracy) and secure communication over >1000 km; DORT‑LVM enables ground‑based large‑volume metrology with >1 km range, µm resolution, and up to 100 kHz sampling for structural health monitoring and digital‑twin creation; DORT‑Sync supplies fibre‑based time/frequency distribution with <10⁻¹⁵ stability and integrated optical path stabilization for research labs and smart‑grid networks; DORT‑Vibe offers non‑contact, multi‑point vibration analysis with >1 MHz sampling and 3‑D tracking of micro‑movements. Complementary AquaTabula software transforms gravimetric data from the satellite mission into high‑resolution hydrological products for agriculture, disaster management, and water‑resource planning. All solutions incorporate atmospheric compensation, onboard data fusion, and secure, high‑speed optical communication, enabling precise measurement and synchronization in both space and terrestrial environments.
Target Audience
Primary customers include satellite operators and space agencies requiring high‑precision formation‑flight ranging and time transfer, infrastructure and civil‑engineering firms needing large‑scale structural health monitoring, research institutions focused on time‑frequency metrology, and governments or enterprises that use high‑resolution hydrological data for water‑resource management and disaster mitigation.
