GNSS Surveying in Honduras: SIRGAS Datum & APS1 Field Guide 2026
GNSS surveying in Honduras uses the SIRGAS reference frame (Sistema de Referencia Geocéntrico para las Américas), the regional geodetic standard adopted across Latin America. Honduras' national cadastral authority, Dirección General de Catastro y Geografía (DGCG-Hn), participates in the SIRGAS network as a regional data processing center, though no public national CORS network is available for real-time NTRIP corrections — making Base+Rover configuration or PPP/Galileo HAS satellite-delivered corrections the practical standard. The APEKS APS1 handheld GNSS receiver, priced at approximately $450, has been field-verified by a real customer in Honduras and praised directly on Alibaba for its accuracy — including elevation measurement.
1. Honduras Survey Overview
Honduras is an active Central American market driven by agricultural expansion, rural land titling, and essential civil infrastructure development. High-precision spatial data plays a pivotal role in establishing clear land tenure for commercial coffee and banana estates, guiding highway rehabilitation projects, and modernizing municipal cadastral systems.
The primary governmental body regulating spatial mapping and land records is the Dirección General de Catastro y Geografía (DGCG-Hn). Operating under the national property administration framework, DGCG-Hn oversees cadastral standards, manages official geodetic control networks, and coordinates national geographic data. In addition, DGCG-Hn serves as a regional processing center within the broader Latin American geodetic structure.
Because traditional optical surveying in Honduras' dense tropical terrain and mountainous topography is labor-intensive, satellite-based GNSS positioning has become the standard tool for local survey engineering firms and independent land professionals.
2. Geodetic Reference Frame: SIRGAS
Honduras relies on SIRGAS (Sistema de Referencia Geocéntrico para las Américas) as its official regional geodetic reference framework. SIRGAS is a modern, 3D geocentric system fully aligned with the International Terrestrial Reference Frame (ITRF) and directly compatible with WGS84.
Historical geodetic surveys in major urban centers such as Tegucigalpa established local primary control networks using high-precision static GPS tied into the SIRGAS network (specifically referenced to the IGS05 realization at epoch 2010.55).
For modern engineering and boundary projects in Honduras, field teams collect positioning data directly in WGS84 / SIRGAS UTM Zone 16N coordinates without requiring legacy datum transformation parameters.
3. No National CORS: Base+Rover and PPP/HAS
Unlike some neighboring Latin American nations, Honduras currently lacks a public, nationwide real-time CORS network broadcasting free NTRIP correction streams to field surveyors.
Consequently, professional field operations rely on two primary workflows: setting up a local physical Base+Rover radio link or utilizing autonomous PPP (Precise Point Positioning) and Galileo HAS (High Accuracy Service) satellite corrections.
This infrastructure environment makes ultra-portable GNSS receivers like the APEKS APS1 especially valuable. Capable of receiving satellite-delivered PPP/HAS corrections without requiring a physical base station or cellular internet access, compact receivers offer budget-conscious survey crews an efficient positioning workflow in remote rural districts.
4. Field Case: APS1 in Honduras — Real Customer Feedback
A real customer in Honduras has field-tested the APEKS APS1 handheld GNSS receiver and shared positive feedback directly through Alibaba, specifically highlighting the device's accuracy — including elevation measurement performance.
At approximately $450, the APS1 pairs a 210g ultra-lightweight design with a UM980 positioning core, giving budget-conscious teams in Honduras centimeter-level capability via NTRIP where available, or PPP/Galileo HAS corrections in areas without CORS access.

5. Step-by-Step Setup for Honduras
Check if a local project base station or private NTRIP server is active in your working area. Note that Honduras has no public national CORS coverage.
In rural agricultural zones without cellular coverage or base access, enable PPP / Galileo HAS tracking in ApekSurv field software to receive satellite-delivered correction signals directly.
Select SIRGAS / WGS84 as the active datum in ApekSurv, setting the map projection to UTM Zone 16N (covering Honduras).
Perform a check shot on a verified local geodetic benchmark or property monument to confirm coordinate alignment and elevation accuracy before starting parcel demarcation.
6. Key Survey Applications in Honduras
- Agricultural Land Demarcation: Boundary verification and perimeter mapping for coffee estates, banana plantations, and commercial livestock farms.
- Cadastral Modernization: Updating municipal and rural parcel boundaries in compliance with DGCG-Hn guidelines.
- Infrastructure & Civil Works: Topographic baseline surveys for rural road rehabilitation, bridge construction, and irrigation channels.
- GIS & Natural Resource Mapping: Lightweight, rapid spatial data collection for forestry management, environmental conservation, and utility inventory.

8. FAQ
Does Honduras have a national CORS network for RTK surveying?
No. Honduras currently does not operate a public nationwide CORS network broadcasting NTRIP corrections. Surveyors rely on local Base+Rover radio setups or satellite-delivered PPP/Galileo HAS corrections.
What geodetic reference frame does Honduras use?
Honduras uses the SIRGAS (Sistema de Referencia Geocéntrico para las Américas) reference frame, which is aligned with ITRF and fully compatible with WGS84 in UTM Zone 16N.
Has the APS1 been tested by real customers in Honduras?
Yes. A real customer in Honduras field-tested the APEKS APS1 handheld GNSS receiver and submitted positive feedback directly via Alibaba, praising its overall accuracy and elevation measurement performance.
Can the APS1 work without a base station or internet connection?
Yes. The APS1 utilizes the UM980 core board supporting PPP and Galileo HAS satellite corrections, enabling sub-decimeter to centimeter positioning accuracy directly from satellite signals in remote areas without base stations or cellular internet.
