## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GPS-25071:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GPS-25071:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The u-blox ANN-MB5 multi-band (L1/L5/E5a/B2a/NavIC) active GNSS antenna is designed for the new generation of multi-frequency, multi-constellation standard precision GNSS technology, which can achieve the most accurate, reliable, and robust positioning even in challenging environments. ANN-MB5’s compact design, excellent price-to-performance ratio, and easy mounting features ensure a fast, easy, and reliable multi-band antenna solution for mass adoption. ANN-MB5 is a perfect match to the u-blox L1/L5 multi-band meter-level GNSS technology (e.g., F10 standard precision platform), providing you with the ready-to-use, multi-frequency antenna you'll need to minimize the evaluation and design efforts, and speed up time-to-market.
