Aerobits TR-1A The Smallest ADS-B Transceiver for UAV Applications
TR-1A belongs to the second generation of the world’s smallest ADS-B transceivers, developed for civil and commercial Unmanned Aircraft Systems, with weight and size reduced by 33%. Operating on the 1090 MHz band, the device enables both receiving and transmitting ADS-B data with configurable RF output power of 0.25W, 0.5W, or 1W. The transceiver is designed as a fully standalone solution and requires no external devices for operation. It integrates a high-quality multi-GNSS receiver and a barometric pressure sensor, providing accurate positioning and altitude data for advanced UAV operations.
Built with durable aluminum housing and full ESD protection on all lines, TR-1A ensures reliable operation even in demanding environments. The device supports real-time aircraft tracking and paves the way for implementing Detect and Avoid algorithms, enabling the safe integration of UAS into controlled airspace. TR-1A is based on patented FPGA-In-The-Loop™ technology, enabling the reception of thousands of ADS-B frames per second while maintaining low power consumption and compact dimensions. The module supports MAVLink and AERO protocols, simple plug-and-play operation, and configuration via AT commands.
Designed to meet MOPS DO-260B requirements (except output power), TR-1A is an ideal solution for onboard traffic monitoring, position broadcasting, and advanced UAV traffic awareness systems.

Shipping Policy
Fast Delivery! We ship via USPS, UPS, DHL, or FedEx because they're fast, reliable, and easy to track. We process orders within 24 hours, and delivery may take 4-7 working days, depending on your location. We'll email you the tracking info once we ship your order. We sell worldwide and in USD.
Shipping Costs: For some products, we calculate shipping costs by weight rather than quantity. To reduce shipping costs for orders with multiple items, please get in touch with us before placing your order.
Tariff: To minimize or avoid high tariffs, we ship from the country where the product is made, such as China, Italy, Taiwan, Canada, or Europe, etc. If applicable, you will pay the tariff in your country. The total amount of your order does not include a tariff, which you'll pay before the delivery.
Ships From: On this product page, check the Ships From: label to see which country the product ships from. We do not ship all products from the USA (except for products made in the USA or in stock), and we ship some products from regions such as China, Italy, Taiwan, and Europe, etc. Therefore, the tariff you pay depends on the country of origin, as not all countries charge the same rate. For example, suppose the US imposes a 30% tariff on goods imported from China; in contrast, other countries may impose a lower tariff, or even none at all, on goods shipped from China into their countries.
Tariff vs. Shipping Fee: Please don't confuse the shipping fee with the tariff, because they are two separate charges. You pay us a shipping fee for the carrier to deliver your order to your door. You pay the tariff to the customs office, a branch of your government, as an import tax.
Why aren't we adding tariffs to the product's retail price? If all countries imposed the same tariff amount and used the same currency, we would have added that tariff to the product's retail price. Our suppliers and we are not responsible for tariffs. Please shop accordingly.
Attention! We will email you the tracking number so you can follow your parcel. The shipping company will contact you by phone, text, or email to arrange payment of the tariff on their website. However, as the customer, you are responsible for responding to their calls, texts, or emails. You can also use the tracking number link we emailed you to contact the shipping company or pay any applicable tariffs online, if you haven't already done so.
Heads Up! We're not responsible if the shipping company returns your parcel to the country of origin due to the unpaid tariff or non-compliance with its requirements. As a result, you will be responsible for the reshipping costs, applicable tariffs, and an additional 20% service fee. We will not accept any excuses for failing to follow up with the shipping company regarding the tariff, and we will not issue a refund.
Please check your SPAM folder! To provide you with delivery information, we will add your email address to the shipping website so you receive delivery notifications until your parcel reaches your shipping address. Please always check your spam folder to ensure you receive emails from Oz Robotics, USPS, UPS, DHL, and FedEx. Please let us know if you don't want us to enter your email on the shipping company website.
Return Policy
5 Hours: If a mistake occurs during purchase, you have 5 hours to request a refund for any reason, including if you don't want to pay the tariff. However, Stripe will not refund you its processing fee if you cancel your order; therefore, we cannot refund it.
All Sales Are Final: After 5 hours, we cannot cancel your order or issue a refund unless you have decided to buy directly from our manufacturer for whatever reason; in that case, once we validate this with our manufacturer and confirm that it is correct, then we will charge you, the customer, a 20% service fee to process your order cancellation request as an exception. Order cancellations require extra staff hours and incur multiple transaction processing fees from Stripe and PayPal, additional shipping fees, reverse tariff payments, and paid ads, all of which are costly and time-consuming. For technical issues, we'll assist you in resolving problems and provide a replacement if you can prove that the product has a manufacturing defect.
Exchange Policy: We want you to be happy with your new purchase. However, once you have used the product, we cannot issue a refund, but we will offer an exchange for a product with irreversible manufacturing defects or technical issues. If you purchased the wrong product, then you will be responsible for the re-shipping fees and tariffs. If your product is defective, please email us ASAP with photos or a video of the faulty part so we can evaluate the issue before arranging a replacement.

Terms and Conditions
Delivery Date/Time: If the shipping company cannot deliver your parcel because you were not at your delivery address on the scheduled date/time, this is not our fault. If the carrier returned your parcel to the manufacturer from the country where it was shipped, that is outside our control. Therefore, you will be responsible for paying the re-shipping cost and any applicable tariff for any re-shipment request. In such a case, we will not issue a refund.
Product Warranty: Our warranty covers only product-related problems caused by manufacturing defects. It does not cover problems resulting from faulty repair attempts, customer accidents, or misuse.
