在秘鲁部署了一个由高频信标发射机和接收机组成的小型网络，以确定该地区的F区电离层。这一努力的动机是与赤道扩散F(ESF)有关的电离层扰动，特别是通过数值模拟确定的ESF不利条件下产生的扰动。信标以双频(2.72和3.64 MHz)运行。它们是CW，但结合了伪随机噪声(PRN)编码，以便可以测量链路的群延迟。其他可观测的还有功率、多普勒频移、方位和偏振。发射机部署在安康(11°46‘37“S，西经77°09’1”，海拔51米)，接收器部署在吉卡马卡(11°57‘5.8’S，76°52‘27“西经，510米海平面)和环卡约(12°02’30‘S，75°19’15‘西经，3315米海平面)。
A small network of HF beacon transmitters and receivers has been deployed in Peru for specifying the F region ionosphere in the sector. The effort is motivated by ionospheric disturbances associated with equatorial spread F (ESF) and specifically disturbances arising under inauspicious conditions for ESF as determined by numerical simulations. The beacons operate at dual frequencies (2.72 and 3.64 MHz). They are CW but incorporate pseudorandom noise (PRN) coding so that the group delays of the links can be measured. Other observables are power, Doppler shift, bearing, and polarization. A transmitter is currently deployed at Ancon (11°46'37''S, 77°09'1''W, 51 m above sea level (asl)), while receivers are at Jicamarca (11°57'5.8''S, 76°52'27''W, 510 m asl) and Huancayo (12°02'30''S, 75°19'15''W, 3315 m asl). An algorithm for inverting the beacon data combined with electron density profiles from Jicamarca is described. Data and representative solutions from an experimental campaign held in August 2015 are presented and evaluated.
