Industrial GNSS Lock Design Refinement
Budget: ₹1,500 – ₹12,500 INR
I already have the first-pass schematic for my GNSS-based digital lock / data-logging system and now need a seasoned set of eyes to push it to true production grade. The immediate priority is GNSS module integration—antenna design, RF layout, and low-power optimisation all have to be nailed so the unit survives in an industrial environment without dropouts or noise issues.
What I’d like from you:
• A detailed review of the existing schematic with annotated suggestions.
• Concrete improvements for GNSS-to-MCU routing, matching networks, power domains and filtering that reflect proven field experience, not theory.
• Guidance on component choices and placement that balance performance, cost and manufacturability.
• Final deliverables in the form of an updated schematic (EasyEDA preferred), a concise change log, and any supporting calculations or simulation files.
Acceptance criteria
– GNSS lock time and fix stability must meet or exceed the module datasheet when tested with the proposed antenna layout on a 4-layer board.
– Total standby current should remain within the prescribed budget once your low-power strategies are applied.
– All RF traces comply with 50 Ω impedance, properly referenced to the intended ground plane, and pass a quick-turn fabrication DFM check.
When you respond, please reference past work that demonstrates hands-on GNSS or other RF product development; links or brief case studies are ideal. We can step through the current design under NDA once we establish the fit.
