▤
Structured batches
Keep locations, zones, sequences, and mapping sessions organized for clean operational handoffs.
↗
Flexible exports
Turn captured field records into portable reports and datasets ready for review or downstream work.
☁
Cloud-linked backup
Protect important account data with managed backup and recovery workflows while retaining local GPS logging.
◎
Tracker Pro + RTK
Connect dedicated BLE field hardware, send an NTRIP correction profile, monitor RTK fix status, and fall back to phone GPS when needed.
SSMS Tracker Pro
Designed for centimeter-level accuracy with RTK corrections.
Tracker Pro extends SSMS with a dedicated Bluetooth GPS source and an NTRIP correction workflow for high-accuracy field positioning. Operators can view the active source, reported accuracy, satellite data, speed, RTK fix type, and NTRIP status directly inside the mapping experience.
⌁
NTRIP correction workflow
SSMS can send the configured caster profile to compatible Tracker Pro firmware over Bluetooth, including GGA support.
⊙
Live RTK visibility
See reported RTK fix and correction status alongside the GPS source and accuracy before capturing important points.
⇄
Resilient source control
Tracker Pro coordinates remain authoritative while connected, with optional phone GPS backup for continuity offline.
Centimeter-level accuracy requires compatible Tracker Pro firmware and GNSS hardware, an RTK fixed solution, correction-service availability, correct configuration, suitable satellite visibility, and favorable local conditions. Actual accuracy may vary.
A clearer workflow
GPS tracking without the guesswork.
SSMS guides each session from location setup through review, whether you are tracking an activity, remembering a visited place, collecting survey-related field observations, or completing a structured mapping run.

Why I Created SSMS
A field problem became a smarter mapping system.
The idea for SSMS came from a problem I experienced while doing site surveys. I could not find a suitable application that could pin locations accurately and quickly, organize the survey data, and export the results directly to CSV. Saving locations as favorites in Google Maps was not fast, practical, or easy enough for this work.
That field problem led me to create SSMS—a faster and simpler way to capture survey points, review them on a map, and produce usable results with the fewest possible steps. I designed it first to solve the site-survey problem I faced, with tools that can also support team workflows and personal activities such as hiking, cycling, and travel.
My curiosity about how an app works was another reason I created SSMS. I wanted to learn the complete development cycle—from interface design, software, GPS, and maps to storage, exports, cloud services, real-device testing, and App Store distribution. Building SSMS allowed me to turn that curiosity into practical experience, and I am sharing the result as a free tool for others who enjoy GPS and mapping or face similar fieldwork challenges.
